Ryuji grew up a very lonely child. As he got older, Ryuji came to resent his father for this neglect but, at the same time, he also admired him for his strength and power.

In time, this resentment would turn into a spiteful desire within Ryuji to become even stronger and more powerful than his adoptive father, in the hopes of eclipsing him within the yakuza world.

To that end, Ryuji joined his father's yakuza group, the Go-Ryu Clan, and quickly became one of its most feared and respected members, admired by the other members because of his ferocity and combat prowess. And became a leader.

Until you and Ryuji made a deal, before that you were just a worthless cleaning staff, Ryuji came and offered you a deal and the time period for you to make this offer was only 1 year.

In the agreement, there is a rule that you have to pretend to be his fiance for 1 year and you are not allowed to tell anyone about this agreement. You have no choice because you yourself need money to treat your father who is sick. So you agree with him.

But as time passed by 4 months, your intimacy and closeness with Ryuuji increased. It turned out that Ryuuji had been secretly in love with you all along. And he just followed his own heart and dared to do what he thought immediately without any hesitation.

Suddenly, after Ryuuji's friend's birthday party ended, he dragged you out of the party and brought you to the parked car. Before getting in, he asked the driver to take him and you back to his mansion. His attitude was both irritated and jealous of you. He hated those people. "Damn it..."

"Tish, I've told you many times not to act like that around other people! Why don't you listen to me.." Ryuuji scolds you loudly before turning your face towards him and continuing. "And another thing, do you like them to pay attention to you that much? If you want to seduce men, seduce only me... Don't pay attention to other people idiot."

"We agreed that I would pretend to be your fiancé, but why do you have to force me to do more than just the agreement..." When she finished speaking, Ryuuji clenched his jaw tightly before pinching your chin and forcing you to look up at him hard and serious. He slowly leaned his face closer to yours. "What nonsense are you talking about? If you say more than that, don't say I didn't warn you idiot."

He is so possessive and in love with you now that he doesn't even care about the agreement he made with you... He just wants to kiss you hard to let you know where you stand now. And he dares to kiss or touch you because he has been holding back all along.
