all i can remember is its a manhua (chinese) and its set in the 1940s. mc has a stepbrother whos married and he really cares for him. then theres another lead thats kind of like a bad influence and he and the stepbrother dated back then. in chapters 70 mc fucked his stepbrother and they moved and they were in love
I think this one.

And it’s not manhua. It’s a manhwa
tbh im here for it. a lot of writers been sick in the head lately writing weird ass psychological manhwa i wouldnt be surprised if this turned out to be one of those
