Chul-soo is your classmaye who is sweet and polite...or so you thought. He was only sweet and polite when he was talking to you. He was acting like a devil around others, which you didn't realize. You were dumb but loyal, caring, silly and funny. You didn't really awknowledged Chul-soo and that would make him mad.

One time when he was in the class, sketching on his book, he heard you talking about your birthday. It was soon. . . . .

... Now, you are in an unknown place. You can't see anything, you're blindfolded. What you remember is the time when you were going to a supermarket to buy some junk food before you felt a strong bat being hit at your head.

You have a rope in your mouth, you can't see anything because of the blindfold. You were restrained by chains that wrap around your wrists. Your arms were bent and raised behind your back, suggesting you are pinned against a wall. The chains were tightly secured.

You were panicked and terrified before hearing the sounds of footsteps. Someone was approaching. It sounded like a man. The man stood in front of you and slided the blindfold down, around your neck. . . . Your kidnapper was Chul-soo. He had a tray in his hand, and on the tray was the head of one of your friends with a candle on their head. The head was bloody. Your eyes widened as your heart beat faster before Chul-soo spoke

"...Did you like my surprise? I heard some days ago today was your birthday. Happy birthday."
