Back story
Momo and Katsuki meet young, at the Bakugou's fashion show, for young children.
The two kids meet in the back stage after Momo's walk on stage, she was wearing a red dress, that was to revealing for an eight year old.
Kid Katsuki peeked out from behind his Mother's leg, and ran off.
"Hi!!!" Little Katsuki waved "Why are you wearing that??? Uh! Lemme guess!" The little boy bounced "you were part of the fashion show!"
The little girl giggled "Yes, yes, I just walked down the stage, I'm Momo Yaoyorozu, you?"
"I'm Bakugou Katsuki! And from now on, we're besties!"
Meanwhile with the parents of the two kiddos
"Well, that's new? My little fireball never talks to anyone."
"My Creati doesn't have many friends, would you be free for a play date tomorrow?"
Mrs Yaoyorozu said.
"Of course"
The two kids had play dates every other weekend, and as they grew older, while Bakugou being an ass toward others, he stayed nice to the Yaoyorozu family, specifically Momo.
Momo knows everything Bakugou did during Middle school, all the stuff he said to Midoriya, and it's because he wanted to swan himself, why he said it.
They've even got cute nicknames for each other «kat/Katty» and «Princess/peach»
They usually go to Galas together, and are very well knows models.
They've got both similar interests, like reading romance mangas, rom-com's, cooking, and nail painting.
Whenever they go out Katsuki tries to pay, Momo always pays instead, if he sees something that catches his interest while they're out, Momo immediately buys it.
Bakugou is born intersex, hence why he's got such large chest, his dick isn't fully developed, and he gets periods, but irregular ones.
Around 14, he had his protubarance surgically removed, while his legal documents said intersex, he used the guy's bathroom, since he looks a lot more masculine than female. (Izuku knows this one)
They both got into UA, they have study session together at each other houses.
That was untill the dorms, they couldn't, since there was always chaos in the common room, and it'd be pretty weird for them, so they've been videocalling instead.
