"Ushijima!"
"Hmm?-"
"Ushijima! Wait- wait for me!"
"Sorry, was I walking too fast?"

You stopped running and tried to catch your breath

"Hah..hah...hahh.. Yeahah... Kinda.."
"Oh, sorry"
"Please.. Try and get your long ass legs to walk slower?"
"Okay, will do. Come on"
"You better slow down"
"I will"

You both walk each other home, I mean, you both were just next door neighbours- today you both were assigned to do a project, you've both settled that Ushijima will do the research and you will write everything needed

"Hi Wakatoshi!"
"Hello Mrs. (Mom's name)"
"Wakatoshi, I told you to call me by our last name!"
"Oh, yeah, I forgot that. I'm sorry Mrs. (L/n)"
"It's alright! Besides, you've gotta get used to that last name since you might get your last name changed into it!"
"Mom!-"
"What?! I'm just informing him something that might happen!"
As you two were blabbering about to not mention anything about that, Ushijima just stood there with a slight blush on his cheeks.

"We're gonna go do our project now mom"
"Okay! Make sure not to make kids! Which is very impossible since you're both men- DON'T TRY AND ATTEMPT IT YET!"
"MOM!"
"OKAY- I'LL SHUT UP-"
"Don't worry Mrs. (L/n), we'll make sure not to attempt that any time sooner"
"Good Wakatoshi! Just call me (L/n)! Or mom if you'd like! My future son in-law"
"Mhm!"

You both got to your room and then you glanced at Ushijima.

"Hun."
"Hmm?"
"Don't keep on encouraging my mom please."
"I'm not encouraging her, I'm just letting her know that we wo-"
"ATTAT-TATATAT"
"...I'll shut up."
"Thank you"

The project making was.. Silent and- awkward-..

"Ushijima"
"Hmm?"
"We should take a break"
"Okay"
"Do you want me to get snac-"
"No need to worry about that!"
"DAD?!- WHEN DID YOU GET HOME?-"
"Just now, your mother told me to give you snacks."
"Okay, thanks dad"
"No problem" *👍*
*👍*

Ushijima looked at your father and smiled, your father smiled back. They both almost have the same energy, which leads to your mother telling him that Ushijima acts like your father every time he stays for dinner

"You both have a great relationship for a polar opposite father and son"
"Ushijima, we're polar opposites and we're dating"
"Still"
"Okay- NOW!-"
"hm!-"
"Sorry- lets eat!"
"Okay!"
"...THAT WAS ADORABLE-"
"please tone it down-"
