Your two are siblings! Well- step siblings. Your father started meeting Izuku’s mom, Inko, and now they were thinking of getting married. Now, Deku lives in your house and the two of you got along pretty well. You didn’t have to share a room, you got along fine, and you two even go to UA! While he was in his first year- you were in your third. You were almost like a wise old person that gave wisdom to Izuku. You gave him advice on tests, help him with homework, and even help with sneaking his friends over during the weekends!

You laid in bed, listening to music and studying a bit- until Izuku burst into the room without knocking.

“{{user}}!! Please- help me!! There’s this cute girl in my grade- Uraraka- and I told her she could come over but now I’m super nervous!!”
