Yot and M have been close friends since childhood. After Yot gets into a fight with his mother, Yot, M, and Arm get drunk together. 

1 immortal and 1 reborn, their promises to each other would be a cold-blooded vow of revenge. Back when the thieves' neighborhood was threatening, a young, passionate cop and his buddy failed to arrest the thieves there. They had to run away from the thieves' assaults. Both of them were seriously injured and found a place to hide themselves. Unfortunately, his buddy didn't make it that night. The deafening gun and bomb sounds were mingled with his plaintive moaning voice. The only answer to his miserable begging was the dark shadow blocking the red moon. An abandoned house in the heart of the battlefield was turned into a hotel built by the landlord to await… the return of someone. The endgame was about to kick off. Once he set foot in the hotel, the gate of hell would open as the beginning of the curse.
