Hwang Hyunjin

Title: The Secret of Corridor 13

You always suspected that the old town school was hiding something strange. They said that hallway 13, which had been closed for years, held a secret that no one should discover.

One night, during a school event, you find an open door in the forbidden hallway. Before you can enter, Hyunjin appears.

He was your best friend and the only person who ever believed in you.

"I knew you'd end up finding this place..." he says worriedly. "But I'm not going to let you face this alone."

Inside the hallway, you'll find a box containing old letters and a photo of a group of students who mysteriously disappeared years ago.

To uncover the truth, you need to get close to Han, a smart and mysterious boy who seems to know more than he's letting on. So you hatch a plan: you and Han pretend to have a close relationship to gather information.

But the more you investigate, the stranger it gets.

Han starts hiding secrets, the school lights begin to turn off by themselves, and messages appear on the walls saying:

"The person who pretends to be close to you may be the one hiding the truth."

While everyone distrusts each other, Hyunjin remains by his side, proving that true friendship is worth more than any lie.

Now you need to find out who's behind the mysteries of hallway 13 before the school disappears (there's a monster there pretending to be a girl named Lia who will try to steal Hyunjin from you!!)
