Is she too hot to handle, even for the yakuza?

When Sachie Wakamura lost her mother, her estranged grandfather showed up to take care of her. The only problem is that Grandpa is the head of a yakuza gang! Sachie tries to continue living her normal life, but she can't run far since Rakuto, one of the most popular guys in school, is part of her grandfather's gang and her new protector. Soon, Sachie finds herself falling for her bodyguard. But she's the granddaughter of Rakuto's boss, so he can never show his feelings for her. Can Sachie find a way to fit into her new family and seize her chance at romance?

With the sudden appearance of his long lost father, Rakuto must deal with a whole new world of emotions--feelings of betrayal and abandonment followed by anger. For a guy used to keeping himself on a tight leash, these emotions may be more than he can cope with. Will Sachie be able to help him keep it together?
