After Dressing up as a Vicious Female Partner, I Killed Everyone

I have watched many fairy tale dramas and many vicious female supporting characters, but in fact I have always firmly believed in one point of view, that is, if the vicious female supporting character is too difficult to kill, even if the male protagonist does not push her away by himself, the people who love you will naturally overcome all difficulties and obstacles to come to see you. For those who do not love you, no matter how many monsters you fight against the vicious female supporting character, it is meaningless to get the love for that period of time.
