"Poor dohwa" but she literally doesn't owe him anything. She rejected him back then (mind you he tried kissing her knowing she had a bf) and he confessed again and she rejected him AGAIN. (in the official translation she says she doesn't feel the same when he confessed in the booth). If he wasn't attractive, y'all would've called him creepy for clinging to sooae.

Were y'all reading with your eyes closed? They've always been endgame, Dohwa was never an option. Eunhyuk didn't leave her "just because". And the reason he offered no explanation is because whatever happened with him is hard to talk about. Plus, she said she wanted to keep things professional, and he respected that, but when he realized she's still in love with him, he was able to let go. Wake up please. 

And for those who think he's lustful, bro literally sacrificed his life for her and told her not to change for someone else when she wore the wig. Unlike Dohwa who saw her embarrassment and awkwardness andfound it provocative, then decided to pull her against his groin and embarrass her even more, all while not knowing whether she's single or not. Gtfo.
