House of Horrors

This takes place after the war ends.
Most heroes have decided to go to therapy and try to heal from everything they had to face in the war. Todoroki's husband, Deku, convinces him to try therapy, to help with all the trauma he faced as a child and as a teen. Todoroki goes weekly, but it's hard for him to trust people, so his therapist suggests he write about his childhood so that they can discuss it in their sessions. He doesn't really understand why she has him do this, but she says it might help him talk about it. After some very hard sessions, he's finally starting to get better. He decides to go one step further and write a book about it.
