Everyone knows that Kise Ryota is a peculiar guy who loves recklessly testing the limits of how much trouble he can get into. Their first meeting. He is pressured into dating by his number-one fan, the daughter of a powerful family. She single-handedly beats ten muscular brutes to a pulp, then gives him a sweet smile. He never expected that after rescuing the damsel, sending the kid home would bring him an even bigger headache. But he's free-spirited to the bone. A rich heiress? Too much trouble! It doesn't fit his breezy image, so he firmly turns her down and keeps his distance. Their reunion. A broken bed in a dark basement, the air thick with decay and rot. The little hero, Mitsui, lowers his eyes in despair. Someone so sunny has become the rotting, foul-smelling mess before him. Why? Why did you get involved with F? She demands, then breaks down sobbing. He smiles, his gaze lingering on the girl silhouetted against the light, as if they were back in those early years. Why? His two older sisters had been used as bargaining chips to threaten him. He had no choice, despite all his schemes and efforts. You've got to be kidding! The underworld? A fight over money and power? What could she possibly use to compete with her? She is the legitimate princess of the Mitsui family, the younger sister of the next head of the family, and the heir to the Ogawa dojo. The underworld and the legitimate world both have to show her some respect. Her godfather and maternal uncle, Rukawa Ren, is a business tycoon whose every stomp can shake the national economy. She won't let them get away with this! It's easy to deal with outside enemies, but hard to stamp out trouble within. He suffers, goes mad, and hurts himself. In rage and pain, she hits him, then hugs him and cries with him. He bites her in several places. No matter how much it hurts, she mustn't give in. Later. Sunlight returns to his smile, and the supermodel makes a comeback, more dazzling than ever. In a white wedding dress, she passes him with a bouquet in her hands, happily marrying someone else. He forces a smile behind his mask, unable to offer his blessings. All those years he was away, her love for him had become something he could never give up.
