None of these guys are good for Kyung. I hoped Dong would've been different, would've saved and protected Kyung from Yule and his brother, wouldn't do anything Kyung didn't feel comfortable doing but nope. Sadly he's just like them. He doesn't force himself on Kyung but he's manipulative. I'm only on chapter 53 so I guess it's wishful thinking that Kyung would drop all their numbers and move far away where (hopefully) none of those guys would ever find him again and he could live a peaceful life either alone or with someone who truly loved him.
Oh please don't let anything bad happen to her. I know she can protect herself but I can't help worrying for her.
