"To my, music is my girlfriend, my lover," he revealed.  "Because of that, there are times I get mad and times I like it so much and love it.  I think it's similar to dating."  Jun Hyun Moo asked him, "When you meet up with Zico, do you guys talk about girls?"

Crush replied, "We do.  These days, we say how Red Velvet are pretty."  Dongwan told him, "I don't mean to say you should date all of them, but you should meet many [women]."
