I completely understand that not all people celebrate Christmas. This is just a filler chapter and you can skip if it's against your beliefs or religion <3

I read a fanfic ages ago that had a similar idea. I completely forgot the name and author so all credits to them <3

15+ kissing scenes ahead💋⚠️

Timeskip
Christmas Eve 9:00am
Keigos apartment.

(Y/n) sat crouched on the floor adding presents to the bottom of the Christmas tree. Lights and ordaments were hung all around the tree as well as a typical star on top.

Keigo had yet to come home from work but would be back soon and (y/n) was very excited for him to see her decorations.

She stood from the ground and stared with her hands on her hips at her very hard work. She had spent the last couple of hours decorating, baking food and wrapping presents to make keigos apartment feel Christmas-ey.

Keigo had informed her a few months ago that he hadn't experienced a traditional Christmas since he was 5 years old. He never received presents or was filled with "jolly spirit" when he worked for the commission, so you had set out to make sure he got to this year.

Keigo <3

Hey angel I'll be home in 5 minutes <3

Okay :). You have to knock and wait for me to open the door alright?

Are you hiding a body from me angel?

Not this time, I have something planned :P
————————

Hawks chuckled to himself as he flew through the sky towards his apartment.

Once he made it to the top floor, he made sure to do what he was told and knock and wait to be let into his apartment. He heard the lock turn as you stepped out of the door and instantly closed it so he couldn't see inside.

"What's going on angel?"
He asked with confusion laced in his voice

"First off"
You stood on your tippy toes and pulled him down to you and placed a kiss on his lips.
"Hello, how was work."

He kissed you back with a smile on his lips. He loved dating you, he could kiss you whenever now. He didn't even have to be drunk.

"Great, A UA student I taught last year has come back for internships. I can't wait for you to meet him."

"Me too, I'm sure he's great. Okay and second you have to close your eyes okay?"

"Okay I will"
He closed his eyes as he felt you grip his hand with yours. The door clicked open and he was led inside.

"I don't know if I should trust you or not kid"

"You have to"
You said as you continued leading him until you both stood in the middle of the living room, in front of the tree you decorated.

"Okay you can open you eyes now"

He did and was stunned to silence. You had spent the day decorating his apartment just for him.

"Angel I- I love this holy shit you did such a great job"
He said as he turned around admiring the rest of his apartment.

You still stood next to him with a smile on you face, happy with his reaction.

"I'm so glad you like it."

"I do I really love it angel. I can't believe you did this for me"
He said as he turned to you and picked you up in a hug.

You laughed at his gesture
"You deserve a Christmas kei"
——————————

The next day you woke up in keigos arms, as you had for the past two weeks. It was reassuring. That even if you had a shit day at work or just weren't having a good day, that he would be there that night.

You managed to slip out of his arms without waking him and walked into your kitchen to make breakfast.

Before you met keigo, you spent your days focused on work. You got to choose your own hours and designed and created close, which was your joy, for employment.

But it was always just you. Just you in your apartment. Just you on your way to work. Just you eating lunch. But now it was just you and keigo.

You finished cooking the bacon and eggs and served them onto a plate. The smell must of woken keigo as by the time you took the plates to the table he was walking out of the bedroom.

"Kei you're up I-"

Instead of a greeting back, you received a long passionate kiss. Keigo pulled you onto him and placed his hands loosely on your waist as his lips moved against yours perfectly. You hummed against his lips and you felt his morph into a smile.

When you managed to pull away, you were out of breath.

"Well good morning to you too"
You said with a laugh.

"We can make out later, okay kei. I made breakfast."

"I'm looking forward to it"
He kisses your lips again and says Thankyou as he sits down and begins eating his breakfast.

"Jeez you never fail angel"
He says referencing to your food.

You both finished eating and are both now sat on the couch, ready to open presents.

"Okay here you go, you're first"
You say as you hand him one of his gifts.

It's a small velvet ring box.

"I really hope you didn't spend a lot of money on this angel"
He says.

"Anyway cmon hurry up and open it birdie"
You say avoiding his comment.

He does as he's told and is immediately shocked with what he sees.

Inside the box is a titanium ring. Small intricate designs are along the outside as well as "keigo" with a small love heart
Engraved on the inside.

"Angel- I. This is beautiful I love it oh my god."
He immediately slips it onto his finger and pulls you into him for a hug.
"I can't believe how amazing you are. Thankyou so much. I'll wear it everyday."

You chuckle.
"Your welcome, you better"

"Okay my turn. I think it's quite fitting"
He hands you a box identical to the one you gave him.

"I'm assuming you stupidly spent a lot of money on this kei"
You said.

He rebutted with the same reply
"Cmon hurry up open it"
In the same tone.

You open it and are met with a ring with a row of small Diamonds on top and similar  to the one you gave him "angel" is engraved with a love heart.

"I guess we had the same idea"
He states.

You jump on him and smother him with a hug.
"Thankyou so much kei, I love it. You're amazing."

A few more presents are exchanged, from keigo to you, a necklace with a love heart, some fancy fabric for your designs and some records from your favourite bands.

And from you to keigo, a voucher for his favourite lunch place, a limited addition endeavour figure that he had yet to collect and now finally, your last two gifts.

You handed him a rectangular box with a ribbon around it.

"Okay this one has two parts."

H opened it up to reveal a new visor. Similar to his yellow one that he wears on patrol but more advanced. A designer brand is written on the side as well as small buttons located on either side.

"The glass is crack proof, now there's no way some villain can smash it and your eyes won't be at risk, and also, I got the designer to add some cool ass technology stuff so there's a feature that picks up heat signatures and everything, I wasn't paying that much attention"
You chuckled.

"Kid you just keeps getting more amazing. These are the coolest!"

"Okay wait there's more."
You handed him a large gift that was soft and covered in wrapping paper.

He began ripping the paper and his jaw immediately dropped at the sight.

"You.. made me a new jacket."
He pulled it out and held it in front of him admiring all of your hard work.

For the last couple of weeks, ever since you went shopping with mirko and stopped at that small fabric store, you've been stitching and creating a new jacket for keigo.

It was very similar to his old one. Fur lined the inside and tan cotton on the outside. But this one was different.

There was no holes or scorch marks on this one. Only neat sewn lines that connected the fabric perfectly as well as added pockets and on the inside near the corner "keigo <3" was sewn, just like it was engraved on his ring.

Tears began to fall from keigos eyes as he frantically tried to wipe them.

"No why are you crying"
You leant over to him and tried to comfort him.

He pulled you into his lap without a second thought and snuggled into your shoulder, leaving it soaked with tears.

You ran your fingers through his hair to calm him.
"I love it angel. So so much."

"I'm glad you do kei, but why are you crying"

You pulled away from his shoulder and looked him in the eyes.
"You took your time to make this for me and I just love it so much and.. and your just so great"

"That doesn't mean you have to cry. It makes me sad. I'm glad you love it. I enjoyed making it."

You spent the next ten minutes cuddling in keigos lap. Once his tears died down he began placing small kisses along your neck and jaw which made you laugh.

He placed them all along your face, your red cheeks, your defined jaw, your soft lips, anywhere he could to show his affection.

And you kissed him back with just as much admiration.

Keigo loved when ever you would tangle your hands with his locks. And it would become a tradition for times like this.

One of his hands was placed on your thigh and squeezed softly every now and again.

You both pulled away though at the sound of a knock at the door.

Keigo chose to ignore it as he pulled you back to him, with chest pressed against each other to rid any space. He wanted to keep touching you, kissing you, anything to show his love and thanks.

But once the door knocked again and you placed a final kiss on his lips before standing.

"Oi birdie let me in already"
Dabi's voiced echoed through the door.

"I'm going to kill him"
Hawks said, mad that his childhood friend took the time to interrupt him.

"Calm down baby I invited him."

You opened the door to the scarred man standing outside your door with a bag.

"Jeez took you guys long enough, sorry to interrupt the make out session"
He laughed.

"We weren't making out"
You tired to deny it.

"Yeah nice try, your face is red as all hell and big bird here is giving me a death stare that means he's going to beat the shit out of me."

"Correct"
Keigo added.

"Now do you want your presents or not?"
Asked touya.
