This is very broad, but basically the top is the step brother and the bottom is the mc. The step brother like ignores the mc so he gets mad at him and keeps like pushing his buttons and I THINK he asks the step brother to fuck. So they fuck. I think it was a Chinese manhua? Im not sure though at all, the art was like a 6/10, but great but not the worse.

Its not fake romance
