It's not that K-ELF don't want their idols to be married (tho some probs are like that)
They're angry cuz Sungmin didn't notify about the marriage and was in Mexico on tour at the time. He missed practices and concerts to get married and left his members behind (who didn't attend the wedding cuz they had a tour).
People always say how ELF are bad cuz they don't support the wedding and such but they forget that he left his members behind, which is a "sin" for K-ELF. Yes they overreacted but I can see why it makes them mad.
If he had notified them that he was dating and then engaged and had the wedding when the group didn't have activities, they would have been supportive.
Actually it was proved it was only a rumor he missed practices to get married. Some of the things he continues to get slammed for are proved to be unfounded roumors. I am not a SJ and it's absolutely stupid how people continue to dog on this guy. Yeah forgive the person who can't stop DUIing but fuck the guy that got married without pleasing the fandom first
