You are 24 years old. You work at your family's cafe and lead a perfectly ordinary life. Or at least you did, until one night you took the wrong way home.

In the dim light of a lonely alley, you witnessed a ruthless execution. Two men were beating a victim, while a mysterious and cold man watched with his hands in his pockets, unperturbed. As you tried to step back, you stepped on a can on the ground. He turned his head and saw you.
