It might be an unpopular opinion, but whatever she does is her business. Korea media need to stop over reacting to everything and let them be. Otherwise it may push them even closer together especially when someone's protective instinct kicks in.
From the last round of accusations and the so called evidence presented, i didn't see anything out of the ordinary other than a typical guy having a night out with his team mates and the usual entourage/groupies that comes with such Hockey Teams during their down time. If they didn't have any girls around on such nights out then I'd be seriously surprised. Boys will be boys. If he didn't participate on these typical team building things, he might being outsted from the team for behaving like he is better than everyone else.
One thing I will say though, romantics and kind people often get taken for granted, but if you have not been hurt, or loved, you haven't lived. It is all part of the messiness we called life.
