What if?

Girlfriend?!

3 days later

S/n's birthday was just around the corner and bsf/n was getting married soon. Well, next month to be exact, S/n had invited both the twins for his birthday and they agreed. Y/n didn't think they would agree but they did. Y/n and s/n went shopping for s/n's birthday. Y/n was happy s/n will now be going to school and y/n would probably go to college but she wasn't sure. She had a job that she couldn't quit because she loved it and it paid her well but she also wanted to learn more and on top of that Atsumu had entered her life once again. She was so confused. *Sigh*

"Mommy stop thinking too much, everything will be alright and I want you to be happy on my birthday!" S/n said pouting.

"Okay, okay! Mommy is happy now!" Y/n said sighing and smiling at him.

"So then I told them that- oh hey! y/n" Osamu said out of nowhere.

'Any minute now' s/n thought.

Then Atsumu glared at Osamu,

"Again it should be thank you not I glare at you." Osamu said and walked towards them.

"Hey, what are you guys doing here..?" Y/n said awkwardly.

"Oh just passing by this store, " Osamu said.

"OJI-SAN!" S/n said running towards. (Oji is what you call your uncle in Japanese)

"So hey what're ya up to?" Atsumu said walking towards y/n.

"Nothing much just here to buy some groceries and order a small cake for s/n's birthday." y/n answered.

"Hm want me to help?" Atsumu said but he was nervous.

"Oh sure why not!" Y/n answered smiling.

"Mommy can you pretty please surprise me with a cool cake on my birthday. I'll go play with Oji-san and you can buy a cake with oij-san's brother!" S/n asked.

"Oh uh...Sure?" y/n said looking at Atsumu with a confused face, he smiled and nodded his head.

"Hey, little guy? How come you're not my fan anymore?" Atsumu said, pouting his face.

"What do you mean I am :<" s/n answered looking at Atsumu.

"Well then give me a hug?" Atsumu said, opening his arms.

S/n ran towards him and hugged him. "Aww, man back off yer the baby here," Osamu said, annoyed.

"Shut yer traps samu!" Atsumu yelled back.

"Okay have a fun little guy!" Atsumu said, patting his head.

S/n smiled and waved them off. They went to Atsumu's car but then a bunch of his fangirls started coming towards him with a camera in their hand.

"I'm a big fan of you!"

"Can you sign this please!"

"AHH it's my dream to meet you!!"

"My brother loves you games!!"

"Can I take a picture with you?"

Y/n flinched because so many people were crowding them and y/n didn't like crowds. She was pushed back from his fans and Atsumu saw as she was going out of sight.

"Could you kindly give me space because I'm on a date right now?" Atsumu said smiling but his aura was dark.

"HUH WITH WHOM!" A girl shouted.

Then he walked towards y/n and held her hand and y/n looked at their hand then at Atsumu.

"Her." He answered.

"Me?" Y/n said softly.

He looked at y/n and smiled at her,

"Now leave me alone please." He said smiling, his aura turning dark again.

They all left and y/n looked at Atsumu, "Since when were we on a date?" Y/n asked Atsumu with a questioning face.

" You know I needed help," Atsumu answered.

"Don't use me like that again." She said to him.

"Geez, scary." He said.

"Uhm excuses me Mr. famous please let go of my hand will you?" Y/n said pointing at their hands holding.

"Oh oops sorry." He said letting go of their hands.

"Anyway let's go!" Atsumu said, breaking the awkward silence.

Y/n followed him to the car and drove off.

"I can come on the weekends and maybe look after s/n and take him out?" Atsumu said. Y/n smiled and looked down,

"I think he'll like that." Y/n answered and Atsumu felt relieved.

"Okay," He said.

They drove off where Osamu and S/n were and they got in the car.

"So whatcha guys do?" Osamu asked.

"You're making it look like we did something else." Atsumu hissed at his brother.

"Geez yer so boring, some. I thought you guys had a little fun." Osamu said.

"Excuse me?" Y/n said.

"OH MY GOD, NOT LIKE THAT!!" Osamu screamed.

"Guys guys just shut up! Let's just listen to some music." Y/n said.

Atsumu reached for the audio but Osamu reached it before and put his favorite song on.

"HEY, IT'S MY CAR!" Atsumu yelled.

"Whatever. Doesn't matter." Osamu answered.

Y/n's aura got darker and darker. Then she smiled at the boys coldly. "My son's asleep. Don't wake him up okay?" Y/n said to the boys and they nodded fearfully.

*sighs* "I'll put a song on."

Then y/n connected her phone to his car and went through her playlist to pick her favorite song, she played it and Atsumu's eyes widened.

"This song was your favorite in high school, ya still like it?" He asked eyes focused on the road.

"Mhm yeah, I do." Y/n answered.

Atsumu stopped at y/n's apartment and y/n carried y/n out of the car because he was sleeping. She waved both Osamu and Atsumu bye and went inside. Then she sighed, I feel as if we were never apart. Geez, y/n what's wrong with you. He is not the same Atsumu in high school.' Y/n thought. "Anyway goodnight darling, Love you." Y/n said kissing s/n goodnight. She went to her bedroom and shut the door, she showered and changed into her pj's. Then she was drying her hair when suddenly she got a message. It was from Atsumu, she tapped the notification.

'What was that about' y/n thought. tomorrow is s/n's birthday! I need to have enough energy for him. She went to bed and closed her eyes. She took deep breaths and eventually fell asleep.
