Well, it makes the most sense to sympathize with the one being cheated on because cheating is wrong no matter what the cause is. But yeah, there are still reasons and sometimes it's not as shallow as sex.

I think many people don't get to do what they really want and get pushed around so much that they feel like they don't deserve the things they want. And so they settle. That's really what's sad. So yeah, Joonmyun really wanted to put his life back on track and get back the happiness that he deserves. Sadly, though, that's out of reach. :(

I loved your comments! If there's anyone who should be thanking anyone, it's me! /hugs you
