A Pink's latest title track, "Mr. Chu", conveys a girl's feelings over a first kiss. However, the members revealed that they haven't experienced their first kiss, so they think about their fans when performing the main dance moves for the song.
When A Pink guest starred on the April 9 broadcast of MBC's "Show Champion", MC Kangin asked the members, "Since none of you have experienced a first kiss yet, what do you think about when dancing to ['Mr. Chu']?"
Eunji answered, "Since I've already had a kiss scene in a drama before, I can't really say I've never been kissed." She continued, "However, since the other A Pink members haven't had their first kiss yet, they think of the fans while doing the ['Mr. Chu'] dance."
For "Mr. Chu", there's a part in A Pink's choreography where they hold a finger to their lips and point it away as if to blow a kiss while saying "Chu".
