I'm so disappointed you can't read. Why do you think he got drunk? Because he was disappointed. His boyfriend acts all nonchalant on the day that he thought he was finally going to have sex with him, making him think he doesn't find him sexually attractive. Why do you think he made the suggestion to the other guy? Because the guy confessed he also liked him WHEN THEY WERE BOTH DRUNK. Ayeon didn't think about why it might be a bad idea to let the guy he likes go drinking while he's so disappointed? He didn't think that Woori would be disappointed? How cruel. Ktbn, dfba.
I get your point, but, with that logic, cheating is justified, and I'm sorry, but it's not. That's not how you do things. You communicate. If you are tired of someone, you break up with them, you don't go and fuck whoever comes on to you. Ofc Aeyeon let him go just like that, he was preparing a freaking surprise for the big day lol Woori made a bad choice and that's that. I'm glad nothing too bad happened at the end.

I'm so disappointed on Woori though. What the hell? I mean, I don't wanna get caught up in things, but I hate when they make light of something as awful as being drunk, annoyed and horny and making do with just anyone even after 3 years of rls with THE ONLY guy whose really loved you (︶︿︶)=凸
