I Dressed up as the Vicious Female Supporting Character in a Sadistic Novel, and I Only Cared About Showing Off, but the Male Protagonist Stopped Doing It.

The day I dressed up as the vicious female supporting character in a sadistic novel. He is participating in a love show, destroying the relationship between the male and female protagonists. But I am not the original owner. I messed up and even started to bring them together. But the male protagonist blocked me, "Play hard to get?" I ignored him and continued to match him. Later, he became anxious and said, "You flirted with me but you don't want me anymore, so why are you acting like a monkey?"
