Hanabi is a Japanese/Korean girl who was born with a severe curse of bad luck. During her childhood, she came across an old lady who gave her a special bracelet to suppress the misfortune. However, the bracelet didn't actually get rid of the bad luck; it only suppressed it, and throughout her life, things have never stopped getting worse. But her entire life is about to change by fate when she meets a very strange guy named P—a man of thrills. Things are either now going to go up and down even more, and there's far more to him: THE UNDERWORLD. At least she remains alive.
