quick recap on my knowledge of the DD au (I'm not too big on it so idk much): there's a despair disease which messes up the characters minds. yeah. DD ichi is a lot more cold and quiet now, almost never talking. when he does its to mock or make others feel bad about themselves; not the teasing he usually does, but actual insults that are usually enough to actually hurt others. teru is infected too and ichis a yandere for him ok
