Okay, I have a question.  I'm new to Thai shows, this being only the second I've seen, and the first was a Boy Love movie. 

Phun says that he and Noh can't be together because he's already had sex with Aim.  Why does his past intimate relationship with Aim keep him from dumping her (who was really annoying, although not as stalkery as Yuri) and moving on with Noh?

The only other show I've seen had a similar relationship.  He had an intimate relationship with a woman, but he was able to dump her and pursue his relationship with the guy.

I pretty much skipped everything that wasn't Phun and Noh because I found the other characters kind of boring.
