After Dahyun walked away, Sana was raging. Her eyes looks as if she's ready to kill.

" I HATE HER! " She whispered scream right at our faces.

Chaeyoung and I looked at each other, both shock and annoyed by Sana's attitude.

" No point hating her, Sana. " Chaeyoung said, patting her shoulder.

" I need revenge! " She exclaimed and clench her fists.

She stood there, putting her hand on her chin, rubbing her chin, like she's plotting a plan.

" You know what, let's go find them first. " Sana said, dragging Chaeyoung.

I followed along.

" Where did Dahyun say she was going? " Sana stopped and ask.

Both Chaeyoung and I shrugged after she turned to look at us.

Suddenly, the cafeteria door swung open and we see Mina, Jeongyeon and Nayeon walking out. Since we aren't in good terms, the three of them walked past us but i overheard their conversation.

" Since when was Momo and Dahyun friends? They study together now?? It was weird seeing her at the cafeteria. " Jeongyeon whispered to Mina.

" Sana. " I catch up to Chaeyoung and Sana and grabbed them by the shoulder.

" I think they're at the cafeteria. "

" You sure? " She asked.

Just then, we see Jihyo walking out.

" Hi Jihyo. " Chaeyoung greeted the president.

She smiled.

" Do you know where is Dahyun? " Chaeyoung asked politely.

" Oh, she's in the cafeteria with Momo. "

" Thank you. "

Chaeyoung thanked her. Jihyo smiled and walked away.

" So... The cafeteria. Let's go! " Sana exclaimed.

We spot them the moment Sana swung the door open, since they were the only people there.

" DA-HYUN YAH. " Sana exclaimed.

Chaeyoung and I facepalmed. We walked towards the two of them and Dahyun rolled her eyes, Momo looked down at the table.

" What is it? " Dahyun asked, annoyed.

Even I'm annoyed at Sana.

" What are you doing? " Sana slammed the table, making all of us jump.

She turned her head to look at Hirai Momo.

" We were talking. " Dahyun replied.

Momo couldn't look at Sana, she just packed up her things and prepared to leave.

" I gotta go. See you later. " Momo said goodbye to Dahyun and walked away.

I shook my head. I feel bad for her.

Dahyun got up and took her things with her. Sana grabbed onto her arm.

" Where you going? " Sana asked

" Class. I'm gonna have to find someone to tutor me if you keep scaring Momo away. " Dahyun said and shook off Sana's grip.

Chaeyoung patted Sana and i followed Dahyun out of the cafeteria.

" You okay? " I asked my best friend.

She nodded.

" I'm gonna go find out where Momo went. See you later. " She rushed out to the hallway.

Sana and Chaeyoung walked out of the cafeteria.

" I need revenge. " Sana exclaimed.

She walked towards the lockers, finding Momo's. She stopped at a locker with the word Momoring on it. She tapped on the locker, and a smirk appeared.

" What are you thinking? " I asked.

" Trashing her locker. " Sana replied, still with a smirk on her face.

" You two are going to help me trash her locker. " Sana pointed at us.

Chaeyoung and I looked at each other.

" Sana, we can't do that... it's against the rules to vandalism school property. "

" Dahyun over school rules, Son Chaeyoung. Let's go. " Sana signaled us to follow her.

" I'm going to regret asking this, but how are you going to do this? " Chaeyoung asked, worried.

" Spray paints will do. After school, we're going to get spray paints from the art supplies room and spray her locker. "

Both Chaeyoung and I sighed and nodded our heads.

The school bell finally rang. Sana said bye to us and walked to her class. I turned to Chaeyoung.

" Are we gonna do this...? " She shrugged.

" We have to, i guess? Sana's our friend. " I nodded my head and both of us head to class together.

after school

Everyone in school has left, even Dahyun and Momo weren't in school anymore. It was already 4:30pm and apparently the art room closes at 4 pm.

" How'd we gonna get in? The room is locked. "

" Bobby pins, duh. We'll pick the lock open like how they do it in the movies. Oh by the way, I'd got Renee and Irene to help us do this prank. "

Renee was quite well-known for being the Queen of pranks in this school and she never got caught by teachers. Irene is her assistant.

" A prank? Really? " I questioned Sana.

She rolled her eyes and started picking the lock with her bobby pin.

While Sana is picking the lock, Renee and Irene arrived.

" Let's get this done quickly. " Renee complained.

" Why are YOU complaining? " Chaeyoung asked.

" Trashing lockers isn't really my thing but I'll do it for Sana's sake. " She answered.

" Thanks Re. " Sana thanked Renee and at that moment the door opened.

Chaeyoung and I are suppose to stand guard while they go and get the spray cans.

Renee and Irene walked out with 3 different colored spray can bottles and Sana walked out with a plastic bag.

We looked inside and realised it was a bag of fake insects.

" Why... does the art room... have those....? " I stammered.

Sana ignored me and the three of them walked towards Momo's locker. Chaeyoung and I watched from a few feet away.

Sana opened the padlock with her bobby pin and opened the locker door, filling it with all the fake insects.

After closing the door, Sana, Renee and Irene sprayed Momo's locker. Sana sprayed BITCH on it.

After spraying, the three of them brought the things to the art room, placing everything in order, pretending nothing happened.

Sana locked the art room door and thanked Renee and Irene. She then patted our shoulders and said

" We're done. Thanks for helping. " and she walked off.

Chaeyoung and I stared at the locker once more. I feel TERRIBLE for not stopping them since i know Dahyun's not going to be happy if she found out i didn't stop it when i have a chance. I feel as if Chaeyoung was worried too, she stood there, frozen as ever.

" I'm.. worried, honestly. " She looked up at me.

I placed my hand over her shoulders and patted her.

" Well, what's done is done.. We can't do anything about it but go home and see what will happen tomorrow. "

Chaeyoung nodded and both of us walked out of the school entrance, not turning back to look at the horrible thing Sana did.
