He doesn’t remember because he got into a car accident, gotten amnesia, but literally only forgot Juyeon & everything he did to him. It was internalized homophobia, Juyeon had gotten drunk and confessed to Jiwook. In turn, Jiwook punished and used it against him. Raping & making him do sexual shit all during fckn middle school. Last time Juyeon saw him before the accident he was left in a bathroom with vibrators inside, someone else found him.
