The next day in the school office, So-Hee admits that she was on the roof with Eun-Joo when she jumped.

Many girls accuse So-Hee of killing Eun-Joo as their relationship had become strained in the past year.

So-Hee finds a dismembered body, possibly Joo-Yeon's, in a classroom locker.

They beg her not to jump but she does, claiming that she is no longer afraid and that she feels good because she won't have to go back to her abusive home.

Yoo-jin used to date Ki-Ho and made So-Hee and Eun-young stop being friends with Eun-Joo.

Yoo-jin says she doesn't want to lose to So-Hee again, who is better at schoolwork, and she and Eun-young decide to pretend to jump.

However, on the day of Eun-Joo’s suicide, So-Hee confessed her pregnancy and swore that she was going to kill herself and take the baby with her.

The two-step into an elevator, and as the door is closing, the girl's face turns into Eun-Joo's.
