Are you being obtuse on purpose? Lol. Or maybe I didn't explain it well enough for you. First, it's clear that BTS are all friends in this story and Jungkook had no idea taehyung kissed all of them? That's weird. Period. Clearly, it was before but why doesn't he know? Secondly, this rating boys he kissed while having a boyfriend, is a shitty thing to do. Especially with people they are friends w, that he didn't know about. It's not cute. There's no world where if you and your so have a friend group and your so has kissed all of them, didn't tell you and decided to rate their kisses online while dating you, would be a respectful thing to do. Even if Jungkook didn't know the people, it would be disrespectful to rate your kisses and on top of that, leave your bf out of the list to be quirky. I know this is fiction and it's not that deep, blah, blah, blah, but this is a toxic thing to do and trying to make it cute and funny doesn't work unless you like toxic relationships.
