Hae Rin, is very much like Chanyeol. She 's passionate about a lot of things: music and arts among others. She displays a really bright vibe and keeps everyone smiling with her quirks, her humor, and her cuteness. Never will you see her sad--that'll just be a little weird. However, one thing that sets her apart from Chanyeol that most people don't know is that: she's actually the type to run away from her troubles and try to forget about them and be strong. Chanyeol didn't like this side of her and found it quite troubling to have a girl friend who rarely says what she really feels. He's afraid that he may already be hurting her but she wouldn't let him know. He's frustrated that she's too hard to understand and it came to a point that he felt like he didn't know her anymore. He decided to break up with her.
