Ok so I said in the foreword in the story itself, that was originally written as a school project. My character AJ was baseds off of Jaeseop from U-KISS, in the sense that he was in a band and he was accepted to Colombia University. 

Sai, on the other hand, is an OC. He is kind of based off of three different people. The name "Sai" is a nickname of someone who was a close friend to me in middle school and we really did drift apart. So we don't even really talk anymore. The other two influences of Sai are my last two boyfriends. One was nice and a sweet and all but as far as a bf goes... not that great. He doesn't care about our relationship really, but at least he didn't cheat on me... Sai only had minimal influence from him. The other guy was a jerk. The only things important to him were drugs and alcohol... and money. So yeah, there's Sai and why he isn't based from a kpop person. :)
