You're walking inside the private school where your twin sister is studying. You've taken her place since she's been in the hospital for weeks because of committing suicide that all because of her bullies. They can't seem to identity that it's not her since you two at identical, you both just differ in both personality.

You walk inside the classroom with all eyes on you, you then walk towards a desk. Later, a group of girls approach you with their devilish smirk.

"So little Yena is back?"
