Characters:

Sang Ki (OC)

Sang Ki is an average girl. She's not the smartest, not the prettiest, not the coolest, she's just average. She has a secret crush on the class nerd. She always wonders why she has to be that one kid in class who likes the nerd and thinks he's really the cutest guy out there. However, there seems to be more to her. Something she's hiding. Something locked away in her heart.

Jinyoung

He's the class nerd. He's the science club president and isn't the smartest, but he's definitely the best to ask when it comes to science. He seems to have a crush too. On someone he shouldn't be looking at. Someone who his eyes are just drawn to. Someone of the same , named Gongchan.

Shinwoo

He's a quiet guy, but that doesn't mean he's not a brave one. He has a crush on Sang Ki. He thinks she's so cute when she sits in class every day. He's still working up the courage to formally introduce himself to her. But he seems to know something about Sang Ki that others don't...or maybe something they shouldn't remember.

Gongchan

He's a cute guy. He doesn't really understand things such as math and science, but he is the most beautiful writer. He wants to find a tutor and is looking around for one. He seems to be nice, but there's something else about him. Something not so innocent.
