Most of us K-drama fans have developed a major crush on Kim Woo Bin as the bad boy high school student, Young Do, in Heirs, but what was he really like in high school? Check out his photos below.

I'm kind of digging those glasses, but I totally prefer Woo Bin's new hairstyle in Heirs (the recent shaggy look in the top right corner). Either way, I can pretty much guarantee that I would have been his secret stalker fangirl if I had gone to his real school back then. What about you?
