(In the novel) technically the mc had a 'romantic' relationship in the past but he's over her now and actually…
May I ask about the romantic he had in the past. By any chance she died or betrayed him. I haven’t read the novel. And I think that the FL here might have the same role as the FL in Blood of youth( romance wise). Correct me if I am wrong.
The ML is a genius of genius. In terms of medical or combat but I haven’t seen such a naive and irritating person ever. You can kill everyone he has ever loved but he won’t take revenge on you and will easily forgive you. So I hated his character. Do consider if you can watch such a character or not.
