Flower shop owner Hanayo Shiratori is rescued from a rowdy customer by a wild-looking bad boy named Kasumi. What's more, her parents are planning to marry her off to this scary guy as part of a business venture! At first, she believes he's just as put off by the arrangement as she is, but when he suddenly declares he'll make her fall for him and starts touching all her sensitive places, he knocks her off her feet. Literally. His touch may be bestial, but her moans are so sweet! Kasumi insists that by the time they walk down the aisle, he will capture her heart!
