Kim Hyun Joong's Ex-Girlfriend?

I've seen this picture long before in various forums and blogs but there's no explanation whatsoever about the girl Hyun Joong's with. A reappearance of this picture in soompi forums caused me to blog about it. Who is this girl? Is she a cousin? A fan? A friend? Or an ex-girlfriend? Leader said that he had a girlfriend from way back, but they broke up just before he debuted as part of SS501. I certainly would like to know if anyone of you has actual proof that this girl in the picture is his ex-girlfriend. That would be really nice to know. As a Triple S fan, it's always nice for me to hear of any information about Hyun Joong's past. Anyway, what do you guys think of the girl? I wonder why they broke up. Hyun Joong has never disclosed the reason, has he?

P.S. I read somewhere that this girl is indeed his EX GIRLFRIEND.
