Even though they tried to give Juwon a bit of a redemption arc, I still don’t like him. He was already making slick remarks before that girl came into the picture, so it didn’t surprise me at all that he was telling Chanyeong’s business to ppl. Jiwoong and Chanyeong are loyal and actually best friends, and they wouldn’t even think to say stuff like that about each other, but especially not behind each other's back. They actually care about each other and treat each other like family. Their friendship stood the test of time for a reason. Juwon was secretly jealous of Chanyeong, but Chanyeong was more mature and just saw him as a good friend. Betraying your friend’s trust over a girl, and for her to not only not have feelings for you, but also be openly using you to get closer to her crush? Pathetic.
Watching someone as they make out, regardless of it being in public, and refusing to look away is so weird. And to then try to justify said weird behavior? Yeah no, he should’ve just looked away.
He propably saw for the first time two people from the same gender. And at this point he doesn't even know he also swings that way so I think it's not that wird that he couldn't look away and was memerized
