I'm staying in my school till late of night. I was alone. My friends who already knew about my plan, warned me about the unseen creatures in this school but I don't care. All I need to study. Besides, ghost didn't exist. Well, I'm not alone though. My classmate, Yoosung want to keep me company.

"Yah, let's go to library." I said to him, and he chuckled.

"Okay."

We climbed the stairs to the second floor and to be surprised, the grill didn't locked, so on with the door. I felt suspicious. But I excused that feels since I'm going to just study this night. A soft but cold wind blew suddenly. I felt strange and unusual.

"Luhan, I'm going to toilet. Can you accompany me?" asked Yoosung. I agree since it's little scary to let him alone. Plus, he's cowardy person. Oh yeah, mention about scary, I don' know why I felt so scared tonight. And the school buildings look very old, not to mention that creepy roots and plants that covered almost half of the building. In addition to make the condition worse, Yoosung still didn't came out from the bathroom after almost fifteen minutes. I understand if he want to.... (you shall know what I mean) but there's nothing can be hear. No water dripping, no toilet flushed sound.

"Yoosung? Are you still there?" I asked, yelling a bit. But no response. I knocked the door but no knocking back. Usually, he will knock back to mention someone is inside. Can't take it anymore, I decided to kick the door.

BAM!!

The door was opened but,

There's no one in.

A new message inbox. I checked it. It's from Yoosung.

>> Hi Luhan. Sorry, I can't go with you tonight. My grandmother was very ill. Mianeh. <<

I'm  frozen. Then, who is accompany me just now?
