I totally agree, people have to stop complaining. Like yes, this is a problem faced in most bl manga, but it's a problem for a reason. People in the lgbt+ are always scared that the person they like is heterosexual, or if they have a partner already. Real life or not, this is a common problem, so it makes sense that the author would want to include this into their story line.

I don't get why are people so critic about manga right now. For me it's getting better and better. Now it looks like the final missunderstanding that we know from every other manga. It's the classic plot element and it works every time near the end of manga. Compared to other mangas the plot is still clear and reasonable. If you are coplaining now, have you ever tried to read 'A Man like You'?
