When I was in 8th grade, I had a crush on a friend of mine. He was a trans man, but at the time I didn't understand stuff about gender (and look at me now!) and saw him as a girl. I ended up hurting him while we were on a field trip.
I understand how Satsuki feels right now. That guilt grew the more I learned about dysphoria, and it became especially horrible when I learned about my own identity and realized I had made him feel the same way I often feel about my own body, along with the rest of the sexual harassment I did that day. I don't know if I'll ever see him again, but I've always been scared of what he might do to me in return if I do see him. I don't expect him to be very forgiving now that I know what I did.
Anyway. I can relate to Satsuki's guilt, and I know how Rika would feel if he was told about what Satsuki thought. This story is very realistic to me. Just wanted to communicate that.
