Dai Shiyuan played with her phone in the room for a while when she saw Shan Yaxin coming in dressed neatly. However, she had changed her clothes and probably had taken a shower.

"Sister Yaxin, why don't you want to sleep in the same room as my brother?" Dai Shiyuan put down her phone and asked casually.

When she heard this question, the smile on Shan Yaxin's face paused, she shook her head and didn't answer.

Dai Shiyuan wisely stopped asking and continued playing with her phone.

Whenever it came to questions about the male lead, the female lead either avoided the topic or changed it, as if the male lead wasn't worth mentioning.

"If my brother asks why you're sleeping in this room, how should I answer?" Dai Shiyuan put down her phone and asked seriously.

"Don't worry about it, I'll handle it." Shan Yaxin calmly smiled, as if she had already thought of this.

Dai Shiyuan had no worries and played with her phone at ease.

It wasn't long before her phone rang.

Dai Shiyuan glanced at Shan Yaxin before answering and said, "Sister Yaxin, go open the door right away."

The other side responded coldly and hung up the phone.

Dai Shiyuan felt that the male lead was still angry, probably because he had been left outside.

Fortunately, she didn't have to face the male lead's anger.

Soon, there were footsteps outside, belonging to a man. They paused in the living room for a few minutes before disappearing into the female lead's room.

Dai Shiyuan quietly opened the door a crack and stared at the female lead's door intently.

She wanted to hear any sound, but there was nothing coming out.

After waiting for a while, Dai Shiyuan's neck became a little stiff, and the door finally moved a bit.

Her heart tightened, and she instinctively closed the door.

Shan Yaxin's footsteps came from outside, seemingly coming towards her.

"Xiaoyuan, open the door." Shan Yaxin knocked on the door and said softly.

Dai Shiyuan waited for a few seconds and then calmed down before opening the door.

Looking at Shan Yaxin's calm expression, she felt uneasy and couldn't help but ask, "Did my brother agree?"

"Yeah," Shan Yaxin smiled softly, and her expression didn't show any abnormalities.

Dai Shiyuan was a bit skeptical.

According to the domineering personality of the male lead, how could he agree so easily?

"I hope my brother didn't lay a hand on you?" Dai Shiyuan continued to ask, her eyes constantly glancing at Shan Yaxin, worried.

"What are you thinking?" Shan Yaxin couldn't help but laugh.

Although Dai Wenhao was used to giving orders, he still had some basic manners and wouldn't hit a woman.

Moreover, when she suggested sleeping with her sister-in-law, Dai Wenhao's face was ugly, but he didn't stop her.

According to the man's arrogant self-esteem, being able to stay overnight here was already "giving her face."

It's just that she didn't care, and it was destined to disappoint him.

Dai Shiyuan was a little embarrassed by the laughter and quickly pretended to sleep in bed.

The matter between the male and female lead has nothing to do with her, and she is not usually one to meddle, but she always unconsciously pays attention to the female lead's affairs.

Dai Shiyuan frowned with her eyes closed, unable to figure out why she became so nosy when she encountered the female lead's affairs.

Obviously, she was supposed to stay away from the female lead from the beginning.

"Xiaoyuan, good night," Shan Yaxin said softly, turned off the light and lay down.

Dai Shiyuan suddenly felt a sweet fragrance, which rushed straight to her brain and made it impossible for her to think.

Fortunately, the bed was big enough and both of them were thin, so they wouldn't easily touch each other.

Dai Shiyuan was mentally excited all day and soon fell asleep.

Listening to the steady breathing in her ear, Shan Yaxin couldn't help but smile.

She thought she would have a deep conversation with her younger sister-in-law, but she didn't expect her to fall asleep so quickly.

Looking at the dark night, Shan Yaxin couldn't sleep, and her open eyes merged into endless darkness, but as long as there was a glimmer of light, those eyes would be brilliant.

After an unknown period of time, the person next to her moved, and their body pressed tightly against hers.

Shan Yaxin's body stiffened and she felt the scattered breath at her neck, shrinking involuntarily.

She reached out and turned Dai Shiyuan's head, planning to close her eyes and sleep.

Before she could even prepare herself to fall asleep, there was another warm breath beside her.

This time, her arms were also hugged by someone.

Shan Yaxin tried to push away, but it didn't work.

As early as in the hospital, she had seen Dai Shiyuan's sleeping posture. Asking to sleep together this time was somewhat inconsiderate.

Shan Yaxin sighed lightly and could only let Dai Shiyuan hold her like a koala.

This younger sister-in-law was the only one in her life who could get so close to her.

Dai Shiyuan was woken up by her alarm clock and, upon opening her eyes, saw that there was no one else beside her. She immediately sat up and quickly changed her clothes.

Normally, she would brush her teeth and wash her face in her pajamas, but with the male lead here today, she couldn't be so casual.

After finishing her morning routine, Dai Shiyuan went to the living room and scanned the area but didn't see the male lead. She asked in confusion, "Where's my brother?"

"He went out, said he had to go back to the company." Shan Yaxin answered calmly as she came out of the kitchen with breakfast.

Dai Shiyuan glanced at the number of servings for breakfast and noticed that there was no portion for the male lead.

She guessed that perhaps the dinner from last night left a psychological shadow on the male lead, so he dared not try the female lead's cooking again.

After finishing breakfast, Dai Shiyuan headed to school.

Shan Yaxin cleaned up the dishes and her phone rang, it was a call from the principal.

"Ms. Shan, some entrepreneurs are visiting the school today. You need to accompany them and convince Mr. Dai to invest in this project."

Upon hearing this, Shan Yaxin lowered her eyes and forced a smile as she agreed.

Not only did Dai Wenhao come this time, but there was another person as well.

Rather than convincing Dai Wenhao, she might as well focus her energy on the other person.

For the school, as long as they get the investment, it doesn't matter who puts in the money.

As soon as Dai Shiyuan arrived at school, she saw several luxury cars pulling in one after another. One of the car owners looked familiar to her.

After thinking for a while, Dai Shiyuan finally remembered that he was the second male lead from the book, named Chen Xiao.

They had met once before.

If it weren't for the second male lead suddenly approaching her to talk, she wouldn't have been discovered by the female lead for lying.

Dai Shiyuan pursed her lips and quickly ran after the car while waving her hand.

When Chen Xiao saw a figure chasing after his car in the rearview mirror and recognized her as the daughter of the Dai family, he stopped the car to the side.

"Miss Dai, we meet again." Chen Xiao smiled, extending his gentlemanly hand. His elegant eyebrows and eyes showed a charming demeanor.

Dai Shiyuan was out of breath from running, so she reached out to shake his hand lightly before retracting it and holding onto her knees, panting heavily.

Chen Xiao didn't rush her and waited until she had caught her breath before teasingly asking, "Miss Dai, is there something urgent that made you chase after me like that?"

It was clear that he was teasing her.

Dai Shiyuan didn't feel disgusted with the second male lead, perhaps due to a filter, and she took a deep breath before asking slowly, "Are you here to attend the investment meeting too?"

"How did you know?" Chen Xiao asked back with a smile.

"My brother stayed with me last night," Dai Shiyuan answered lightly.

She remembered the plot in the book about expanding the library, but couldn't recall when it happened. Now that she had talked to the male lead, her speculation was confirmed.

This scene was a classic jealousy-inducing moment between the male lead and the second male lead, and in the book, the male lead won because he had the female lead's affection.

However, now that Shan Yaxin didn't like the male lead at all and even resisted him, it was likely that the male lead's brother wouldn't win either and might leave in a huff like last time.

Dai Shiyuan couldn't accept the idea of the second male lead winning. After all, the male and female leads were still married, and if the female lead was too intimate with the second male lead, it would surely cause gossip behind their backs.

"I see," Chen Xiao's smile was not as strong as before, and he looked at Dai Shiyuan and said, "Do you need me to take you to the teaching building?"

"Uh...thank you, I would appreciate it," Dai Shiyuan hesitated briefly before happily nodding her head.

She was already tired from running a few hundred meters earlier, and having someone drive her there would be nice.

"It's my pleasure to serve Miss Dai," Chen Xiao bowed and opened the car door.

Dai Shiyuan leaned back in her seat and wished that her male lead's brother could see what a gentleman looks like. Only being gentle, considerate, and funny is the right way to win a girl's heart. Being cold and aloof all the time wouldn't make people happy.

Both of them had similar looks and backgrounds, so most people would choose the second male lead.

Dai Shiyuan let out a sigh and suddenly her phone rang. It was Shan Yaxin calling her.

"Xiaoyuan, you don't have to go to class today. Come and join me in welcoming the school's VIPs," Shan Yaxin said while walking, her previously tight brows now relaxed.

Dai Shiyuan was surprised and asked, "What does that have to do with me?"

Although she wanted to watch the show, she didn't want to anger the male lead.

"This event has your brother participating, and the school hopes you can persuade him to invest," explained Shan Yaxin patiently.

Dai Shiyuan frowned and rolled her eyes in her heart.

This time, she made a mistake.

The female lead was arranged by the school because of her marital relationship with the male lead.

Since she and the male lead were siblings, they were naturally targeted by the school, and as a student, she couldn't refuse this request.

In addition, since it was the female lead who spoke up, she had to go even if she didn't want to.

Dai Shiyuan hung up the phone and rubbed her forehead, saying, "I won't go to the teaching building, I'll go straight to the library."

"Okay," Chen Xiao smiled casually, as if he already understood the reason behind it.

Dai Shiyuan looked out the window and began to feel excited.

If the male lead and the second male lead were to compete and be jealous later, she had to be wise and not get caught up in the fight.

When she arrived at the library, Dai Shiyuan saw that some of the school leaders were already waiting on the side, and she hurriedly got out of the car and stood there obediently.

Many of the leaders greeted her warmly, saying all kinds of flattering words.

Dai Shiyuan smiled and replied one by one, presenting a cute and lovable appearance throughout.

Finally, when the female lead appeared, these people stopped praising her and turned to talk to Shan Yaxin.

Shan Yaxin had seen and heard many of these superficial conversations and responded skillfully, even managing to make the leaders laugh without leaving a trace.

Dai Shiyuan watched from the side, with a look of surprise in her eyes.

This was the first time she had seen the female lead's skillful and versatile abilities.

Her proud and confident demeanor was completely different from her usual gentle and mild manner, more like a businesswoman who could handle things well in the business world.

Dai Shiyuan couldn't help but think of the time when Shan Yaxin often returned home late after drinking, could it be that she went to negotiate business?

Their eyes inadvertently met, and Shan Yaxin saw the surprise in Dai Shiyuan's eyes. She smiled slightly and revealed a gentle expression.

Dai Shiyuan suddenly felt embarrassed as if her thoughts had been exposed, and quickly turned her head to look to the side.

Now all the other investors have arrived, except for the male lead who has not yet appeared.

After waiting for a long time, even past the agreed-upon time, the male lead still did not show up, but instead Yao Lu came over with a stack of materials.

"President Dai said that it's better to rebuild the library than to expand it. This is the plan, and we hope your school can consider it carefully," Yao Lu said coolly. Her sharp dressing made her look very elite, and she deliberately glanced at Shan Yaxin.

One of the school leaders noticed the implications and looked at Shan Yaxin, saying, "Teacher Shan, why don't you persuade President Dai? The library is one of the symbols of our school, and it can only be expanded, not demolished."

Shan Yaxin naturally understood the underlying relationship, and she was well aware that Dai Wenhao was trying to make her back down.

But she was not going to compromise.

"I believe that all the guests who can attend this event agree with our school's expansion plan. Now, please follow me to visit the library together," Shan Yaxin showed a generous and elegant smile, speaking calmly.

Upon hearing this, several school leaders looked at each other and quickly reached a consensus.

One of them said, "Teacher Shan, you should still persuade President Dai. We sincerely hope that President Dai can participate in this event personally."

Shan Yaxin could hear the emphasis on the last four words.

These investors knew how to behave according to the wind, and if Dai Wenhao gave up, it would certainly lead to some people withdrawing from the investment.

"What Dai Wenhao decides cannot be changed by anyone. Please don't make things difficult for Teacher Shan," Chen Xiao said, standing up. There was a graceful smile on his face, seeming to be quite pleased.

Dai Shiyuan roughly understood the meaning behind this smile.

His biggest competitor suddenly didn't show up, and the second male lead unexpectedly won. Being able to accompany the female lead throughout the event was certainly a joy.

He didn't expect the consequences of his actions last night to be so severe, causing the school to lose its biggest investor.

However, the male lead was a little impulsive this time. Investing in this school was not only for financial returns, but also for gaining a good reputation.

Good companies need a good reputation, and how could the male lead ignore this principle?

Hearing Chen Xiao's words, several school leaders looked embarrassed and discussed for a while before they could only back down.

Since the Dai family was not attending, they could only hold onto the remaining investors and make sure that the library expansion was a success.

"Teacher Shan, please take a few distinguished guests inside for a visit."

"Okay." Shan Yaxin smiled lightly, showing no surprise.

Upon hearing this, Yao Lu's expression turned cold, and she shook the plan book in her hand. "If your school gives up on cooperating with the Dai family, you will bear the consequences."

"It's not that we don't want to cooperate with the Dai family, but President Dai voluntarily gave up. We have no choice."

"In that case, don't regret it." Yao Lu snorted and arrogantly left with the plan book.

Several people saw Yao Lu leave and made excuses to leave as well.

In the end, only Chen Xiao was left standing in place.

"It looks like I'm pretty lucky today." Chen Xiao smirked, looking pleased with himself.

Shan Yaxin responded with a light smile.

The exchange between the two looked very familiar, which made Dai Shiyuan a bit uneasy. She asked in a low voice, "Teacher Shan, do you still need me to accompany you?"

"If Miss Dai is willing, I would be honored," Chen Xiao said with a smile.

"Okay." Dai Shiyuan happily agreed.

As soon as she spoke, she felt Chen Xiao's smile stiffen for a moment, probably not expecting her to be so "eager."

"But we should also ask for Teacher Shan's opinion." Chen Xiao quickly added.

"I have no objections." Shan Yaxin replied with a light laugh, turning to exchange a glance with Dai Shiyuan.

Chen Xiao caught this eye contact and felt a bit strange, but since the words had already been spoken, he couldn't change them.

"Mr. Chen, please follow us." Shan Yaxin said with a polite and courteous attitude.

Although the school library was large, it could be explored in an hour.

Dai Shiyuan kept a close eye on the distance between the two men and made sure that the second male lead did not get too close.

Her sister-in-law was not divorced yet, so she couldn't let any man get close.
