Only people you should be doubting are his dumb sister and that dude who tried to get him murdered. Seungho can only do so much with what he knows and his trauma while people are literally trying to ruin and destroy everything while he’s slowly trying to make progress ╥﹏╥
I honestly still doubt Seungho because of all those things he did to Nakyum but maaan it is hard to refuse his actions this time.
