The male protagonist is the elder brother, and the female protagonist is the younger brother. Fake bones + flirting without knowing it + extreme restraint + crazy preference + chasing her husband in the crematorium. Falling in love with someone of the same sex is inherently painful, but what's even more painful is that the other person always calls himself a straight man. I treat you as my wife, but you think I am your brother. He flirted with me openly and secretly, and then ran away after flirting with me. "Brother, what does it feel like to kiss a boy?" Listen, listen, is this something a straight man can ask?
