yo so i'm not completely sure but from what i hv seen on weverse, fans (mainly chinese fan) are getting mad at dohoon from tws that he put the flower carnation thing around ana's neck (search "rude h2h encore" on yt) during h2h rude encore bc it's white day in south korea.
the fans are mad since he did that to ana, not keeping distance between female idols and not acting as an "idol", which imo is not a big deal considering they are mcs who have been working tgt for over a year. they are saying how dohoon and ana are dating but did they forget anas not even an adult in korea yet???
