Honestly, I didn't like the 20 or so version since the beginning and now, I know why I didn't like it. So, if he was your lover, you would've stopped but do you not love him now or what, huh? You will hurt anyone who is not your lover while having sex, is that what you're saying? That's a big red flag, I don't know how the rating is so high.

In my opinion, Jintae is the bad guy, it wasn't the mc's fault. It kinda seemed like R also did something to wedge a fight between them because he said something like, Y, do you really believe it was the boyfriend who poisoned your tea? R has a part in making them hate each other or is that already mentioned?
The mc's friend is so not a real friend. I think what the uke is feeling is valid and if he wanted to break up because their relationship goals don't align then, it's the correct thing to do. Why should he continue to get hurt by the opposite party? If a person dances around the subject of their ex, it'll obviously make them insecure or doubt stuff.
