He didn't know who his dad was so how he could tell for sure that he didn't kill him ╮( ̄▽ ̄)╭ forya
You think he wouldn't know if he killed someone at teach's house...? In fact, teach probably did something to his own dad,before guwon even got there. That's why his brain deleted the memories to protect himself from trauma, as a response he subconsciously tries to hurt others in his sleep.
The MC is really likeable. I don't want him to get Stockholm syndrome. I imagine him getting saved by his friends, getting healthy, taking revenge on everyone (๑•ㅂ•)و✧
