you and shigaraki are best friends. You were the first one to join the league of villains and ever since you guys have been compatible

one day it was that time of the month. Your period. You asked toga to get you some girl stuff and toga came back. Toga told shigaraki about the situation so he stayed in his room researching all about it

an hour later your in bed drinking your cup of hot chocolate when he suddenly walked in

Hay.. so um.. I researching everything about periods and I found out that s£x works! For nine months!
