i dont think you understand what running away means. he left the uke high and dry after pursuing him and making him think something was possible with him. and then ran and had sex with someone else. just because you may not see sex as a big deal doesnt mean you can pursue someone and expect them not to be hurt if you sleep with someone else instead of you.

yeah it looks like they didn't go all the way and yeah, it's not cheating because they are not in a relationship BUT getting his hopes up and then just cowardly runing away is just shitty and even more so with the fact that he knows the pain and suffering Dongho went through when he was in love with Byul, like dudeeeeeee, i didn't like him much at the begining but now? i don't like him at all, he is just playing with Dongho
