I immediately call the number but no respons. After that I pick up my jacket and wear it, a few moment I hear my phone rings. A new message! 

"We're in an empty building near to amusement park. Please I need help but don't call police" the message says. It's Leo.

-*-

Amusement park is kinda far from my house and gosh this is almost midnight. Should I go? Oh yeah I know!

"Hello, Sehun". I call Sehun, the cute guy at bookstore. 

"Yeah nuna wae? I'm with my friends now. Drinks soju. Do you want to join?". Ah this kid.

"No. I need your help...."

"Really?? Okay I'll pick you. Give me your address I'll come as soon as possible".

Duh, but what if my mom knows? Will she give permission? What should I do??!
