He was framed. Taesoo killed and pinned the blame on the clearly traumatised child who was brought along to “toughen him up” since he couldn’t bring himself to kill or harm another person. When he came to after a black out, he asked taesoo what happened and just like now, taesoo pinned the blame on him. The issue is that he felt so guilty that he kept tabs on the child and that he didn’t investigate further once he got some power of his own but taesoo probably killed off all the other men who were there and could tell exactly what happened that day. It’s just really unfortunate scapegoating.
If he was actually the killer and the way he still made him fall in love w him. He totally deserves whatever shit's happenin to him
