I was watching some Behind The Scenes for FRH&S.H.E's new song, Xin Wo. And since Calvin was paired up with Hebe, he was extremely nervous and even practiced the dance with one of the work members. Jiro then went on to tease him about how nervous he was, and then he revealed, "聽說, HEBE一直都是他的偶像吧。" This roughly translates into, "I heard that Hebe has always been his idol."
SO CUTE!
Hebe's lucky that I love her, or else I'd be extremely jealous. I think it's adorable that Calvin idolizes Hebe though.
