Lee Sungjong is described as a bouncy 17 year old, high school junior. He's cute, energetic, and a diva. He has brown hair and almond shaped eyes that sparkle with the innocence of youth. True, this boy is nothing but pure adorableness.

In contrast, there is Kim Myungsoo, a moody, cold 18 year old high school senior who is said to have a heart made of ice. His smiles are rare but his glares are frequent, more or less likely directed toward Sungjong. You see, Sungjong loves to play and bother Myungsoo. Myungsoo found it a burden, but not because Sungjong was annoying. No... Myungsoo found the little boy cute and adorable like everyone else. Sungjong was one of the only people he'd protect with his life. They were best friends, but the burden put on each of their shoulders was the same.

What made the dark, isolated Myungsoo and the hyper little diva Sungjong click in similarity was what was hidden on the inside. Three things about them were alike.
