1.) teasing
"K-Kacchan... stop it already..."

"Mhm? Are you saying something Deku?"

"K-Kacchan!" Izuku whined

Shoto has been watching them for half an hour now, it all started when Katsuki started teasing Izuku for slacking up then he teasingly accused Izuku of gaining weight which made the greenette upset and get all puffy and worked up, very cute but very concerning, also Shoto was really jealous right now so he doesn't like it, either way Izuku was asking Katsuki to stop teasing him, the blonde only gave him a shark like grin before flicking his forehead and laughing as the greenette chase after him with a very flushed face

Hmmm

"I-I caught you s-so you have to stop now!"

"Eh should I? I thought you liked it, after all you did chase after me... hey Izuku you shouldn't do this kinda stuff infront of your boyfriend"

"W-Wha..? What kind of stuff?"

"You know, chasing after other men, I mean I'm flattered but..." Izuku froze in shock before his face exploded with red

"K-Kacchan...!"

"Ouch- hey hey! Calm down Deku Jesus- ow! Ow ow! Okay I'm sorry!-"

"You seem to like teasing Izuku a lot, is there a reason to that?"

"It's fun, that's all" there's red tainting his cheeks

Ah

"Your kink is... teasing" Katsuki sputtered

"The fuck? I-It isn't you bastard! Go away!"

"Ah I see, so you do have a perverted side, how charming, I'll tell Izuku right away-"

"YOU BASTARD GET BACK HERE-"

"Hey Katchuki"

"Yes papa? What is it?"

"You... you like Izukun don't you?" The robot stared at him with a calculative gaze before blinking slowly and then he metal plates on his face turned red and steamed blew out of his ears as he sputtered

"I-Izukun is my p-playmate that's all! H-He's nice o-of course I like him! That's all there is to it father I promise you!"

"Oh? Is that so? Is that really it?"

"W-Wha.. f-father please! Believe me I-I-"

"Then you don't mind if I told Izukun right now that you like him right!"

"I-I..." The robot whined

"Y-You can't let him know or S-Shoucchan will definitely tease me for it!"

"Eh But Shoucchan likes Izukun a lot too right? What if he tells him first" Katsuki Junior grins

"No way! Izukun thinks Shoucchan is a total creep! The first time he met him-"

"Well that was awhile ago, what if he stopped viewing Shoucchan as someone creepy? I saw them playing with each other earlier"

"Ah..." Katsuki Junior blinked before suddenly his eyes turn entirely blank

"I'll find Izukun right now and tell him! I definitely won't lose to Shoucchan father! Just you wait"

"Be careful!" Katsuki smiled

And then he cackled

2.) Nickname
______________

Izuku has been avoiding Shoto

That normally won't be a problem, but it was getting kinda annoying, whenever Shoto calls Izuku by his name, the green haired male puffs his cheeks angrily kinda like a chipmunk, it's cute but he always walks away afterwards, Katsuki was the only one he's fine talking with, he wonders why

"Izuku?" Once again Izuku pouts and then walks away, this time Shoto follows after him

"Can you tell me what's wrong?" He keeps on walking

"Did I do something wrong?" Izuku stops

"H-How long are you gonna call me by that name..."

"Eh?"

Izuku walks away

________________

"I don't understand, am I doing something wrong...?"

"Why the fuck are you talking to me"

"Because Izuku is talking to you, did you notice anything different about him?" Katsuki ponders for a minute

"He's been reading a lot of romance novels lately instead of his horror shit, that's one thing"

"Oh?"

"Yeah he squeals like a fucking pig and rolls around in our bed, then he forces me to read someshit, it's so fucking sappy I don't get why he likes reading that shit, does he want to be sappy too or something?"

"Oh.."

Oh

____________

"What do you want for dinner, Izuku?" No response

"... what does my adorable boyfriend want for dinner then?" Izuku and Katsuki froze in shock before the greenette exploded with red

"U-Um.. um I-I... I um I want soup please!" He said flushing brightly, Shoto smiled

"Next time just tell me if you want me to call you like that okay? You made me worried"

"W-Well.. I-I wanted y-you t-to call me that w-without me telling y-you to... you know?"

"Why?" Izuku pouted

"You wouldn't know why Shoucchan, boys are like that"

"But you're a boy too-"

"Shush!"
