Yikyung that's not something you say to your partner
That was pretty rude, I would've been offended idk how Joobin was fine with it

I mean I'm a little moody when it comes to insults
I lash out immediately if I feel someone is insulting me, so I don't understand Joobin for letting it slide like that
Yikyung goes around analysing everything Joobin says and throws a tantrum whenever he's upset with him
You expect him to be cautious with his words as well
Listen, to have sex with someone is to choose to be vulnerable with them. It requires trust and reliability. Not to mention the emotional investment, even if you're just fuck buddies.
The least you can do when that jerk is saying bad things about someone who's trusted you is to stop him and go ask the actual person for explanation.
Letting other people run their mouths about your personal matters is so wrong and immature. It would've been acceptable if you saw anything suspicious. But he was nothing less than a gentleman to you up until now, so it's not fair to listen to someone else revealing his personal matters. Even if the brother is telling the truth, they are probably information that he wouldn't want to share.
