I believe it's obvious that Damhwa had a tr*sh personality he didn't even like Yugang have done other tr*shy things( what I think)that his family and Yugang don't want him to be that Damhwa with tr*shy personality. ( Also I think Yugang wasn't and isn't as bad as Damhwa. Looks like he's remembering and I don't like it....)
Soooo there's nothing to do just reading ( BL fan )
