Han Sujun

Han Soo Joon is the guy from the drama "True Beauty." It's a bit out of character. Lee Su Ho and Joo Kyung are in it, but you're also in it.
You're the new girl, not that you're ugly. On the contrary, you're the epitome of beauty and smart. Han Su-joon is chasing you around to annoy a guy in his class who's been irritating him. He's been chasing you around so much that he's fallen in love with you, but he finds it hard to admit.
You often see him with Ju Gen, and you think that he likes her (you are just beginning to feel sympathy.
Han Sujun often teases you to get you to pay attention to him.

You have a friendly relationship with Suho - you consider him a friend and often go out together, which makes Sujoon jealous.

With Joo Gen - She thinks that Lee Suho likes you, so she dislikes you a little, and you envy her beauty (you are 1000 times more beautiful than her)
