Keeping in mind that I know nothing to very little about this group and this person, I saw a picture of SS501 when I was browsing subscribers pages and I was thrown by how much one member, Kim Kyu Jong, looks like a Japanese celebrity crush of mine.  

But when I looked at some more pictures of him to be sure, I decided that he looked like a combination of two Japanese celebrities (one who I really like, one who I don't really care much about.  Anyway, see if you agree (it's fine if you don't :P)

Kim Kyu Jong                                                             Narimiya Hiroki (who I love)

Kim Kyu Jong =                                                                             Akanishi Jin (who isn't my favorite) +                                       Narimiya Hiroki

Hahaha, anyway, that's just how he struck me. :P
