Singer Hyunseung uploaded a picture of himself yesterday and was met with a big controversy!

The picture in question was a simple selfie - however, BTOB fans noted that he was wearing a cap with member Eunkwang's name on it that had been a present to him from a fan.

Angrily, the fans wrote, "He ignored the sincerity of the fan who had given the present," and, "Eunkwang, who was the one who received the present, probably also felt embarrassed by this."

However, a few fans were calmer, stating, "Might [Hyunseung] not have posted this to promote [Eunkwang] because they're close and the cap has his name on it?" saying this shouldn't be a problem, that it only shows that the two are good friends.

As this grew to be an increasingly big problem with people posting a screen capture of the picture onto the SNS of the fan who had given the present, the fan has made his or her SNS account private.
