Relationships are a commitment. He chose to be with Nami after Haero left, be it for love or convenience he made a commitment to her. If he wants to try again with Haero for god knows what reason he’s free to make that choice but Nami deserves to be informed and the relationship ended first. Claiming Nami is in the wrong because he has a complicated history with an ex from **10 YEARS** ago is disingenuous victim blaming at best.

You guys can't understand how it feels for us.Always in thought that your loved one will leave you for 'appropriate' gendre.It is not easy especially because Don isn't gay to begin with.They are all at wrong.And honestly wasn't Haero right?He did end up with woman and steady life.If he loved Haero as much as he claims he would try to look for him but he didn't.And Haero is at wrong for coming onto him now.Don is in relationship and it is not okay to make him cheat.I think they are toxic for each other.Don is not gay so he should stay with Nami and Haero should find someone else.I just hope he doesn't commit suicide like that college student he mentioned.
I have read so much BL manga and this is the first where the author has had me raging that the guy better stay with the woman. Nami deserves better than this mess smh.
