2AM's Seulong had some cute complaints about the group's current single.

The star revealed on the most recent episode of 'Strong Heart' that he wasn't very comfortable with their new song yet.

Seulong as well as his other 2AM members started to sing their title track "I Wonder If You Hurt Like Me", but was stopped right away when Seulong raised his hand to tell the other members, "Wait, I messed up." The members then all got up to sing once more, and although they made it til the end this time,�Seulong wasn't satisfied with his performance as he shook his head and stated, "I messed up." He commented shyly, "Ah this song is too hard."

Fellow member Changmin stated,�"This is our comeback in a long while, so we'll re-do it." The group gathered on stage to harmonize once more, and all eyes were on Seulong as he concentrated to get his harmonization right.

In the end, Seulong pulled it off and the guests were warmed by the beautiful voices of the boys.
