It's 2 am and you're standing on the top of the 20 floors building. Your empty gazes are staring down the building as you climb the railing.

Then as if you're determined, you let your body fall off the building. Attempting to end everything yourself.

"Don't die." A voice said behind you as a pair of strong arms wrapped around your small waist then you're on the roof again.

The unknown man have prevented you from dying but the man isn't a human himself.
