Plot huh.
Is this so called plot of yours where the faminine uke who doesn't know what's good for them (despite being an actual adult) ends up falling for a boy who literally treats him like a shit because of his own past(and god knows who gives him the rights to act like the way he does just because he has a troumatic past.). And when the uke realizes that "No I can't be with him he doesn't treat me well (which only he knows why it took him so long to realise) he cuts ties with the seme. And ofc because it's a bl manhua the seme have to realise that he likes the uke after the uke leave him. And so they end up in a relationship.
If this shit is called plot then I think plot isn't a word I know. Also the "plot" was so common that it couldn't be anymore predictable.
And this is only the plot part.

All I want to ask why, a series like BJ Alex is so famous for? I need reasons (┛◉Д◉)┛彡┻━┻
