It's not that I don't like the ending, it just Yoon treasured Woo a lot and they have been together for a long time. Yes, he's cheating but Yul also has bad sides, both in them in wrong. Yoon has such a sad past and he still can't be with Woo, I cried.
i know the relationships between them all mess up especially wonho but is it bad that i want eunwoo make it more mess up, like he's targeting on taeyoung next..
i was ready to tear up at the unrequited part but the 3 characters were so hilarious hahahah(≧∀≦)
