I don't understand it at all, all I feel is how stupid can a person be to stay in a abusive relationship?

people who stay in abusive relationships are not stupid. do not blame it on the victim(niannian). people stay in these relationships all the time because they are blinding by their love for their abuser, every time the abuser does something bad they act nice afterwards and gives the victim a false sense of hope, etc.

Let me get this straight:
Ml want revenge by acting like dad, included male lover. Somehow he really like, come to somewhat love mc. Which made him hope that his dad love him and he love his dad so the situation of ml and mc will be more "realistic with ml's goal.
As for mc, he loved his past master? Past master died, people think he kills his master...ok.
Summary helps so much.
