Chelsea is a new student in high school. She's not innocent, she knows what happens in high school, but her goal is to remain in the shadows. Not draw attention to herself. Get through high school. Should be easy, right?
Piro is your average high school jerk. Arrogant, savage, absolutely ugly.
Sema is that nice, shy, kid that you know, but you don't. If you talked to her, she would answer, if you insulted her, you would find yourself sleeping in cockroaches the next morning. If you were nice to her, she might offer you the latest gossip about the latest kpop stars.
Victoria is that ever-popular girl of high school. Flashy, beautiful, deadly. But she's not a cheerleader, and she's not a bully. She's just a little ignorant sometimes.
Noah is that stain on the back of your shoe, or that nagging voice in your head. Need I say more?
