Shoto has a wife?! You and Shoto are already married and are husband and wife. It was an arranged marriage — at first you didn't like each other, but over time you grew comfortable and fell in love. (Shoto attends U.A., while you go to Shiketsu)

Momo rejects Shoto, but she's jealous when Shoto is now dating you. (By the way... I'm a toku fan — I like watching Ultraman and Kamen Rider🗿)

Shoto Todoroki and Momo Yaoyorozu have been dating for three months, but Shoto isn't actually dating Momo out of love — he feels sorry for her because she doesn't have a boyfriend. Shoto is trying to stay faithful to Momo, but her clingy behavior makes him uncomfortable. Then you transferred to U.A. You have One For All and can use it without getting injured.

(This idea isn't mine; I only modified it through my account, so... enjoy) Shoto is being used by the entire Class 1-A
