The Classroom

Before he died, that person warned Tang Huai never to enter the classroom again.

It had once been the place where the two of them met. Suddenly, it became forbidden ground at the high school.

Half a year later, still suspicious about her boyfriend's death, Tang Huai returns to the place where it all began, only to be led into that classroom once more.

She wants to know what really happened.

A wild imagination, but poor writing. I can't really create a creepy atmosphere, so let's just see how it goes.
