Souryuu Riku (Suzuki Tatsuhisa), the oldest son of a poor family with many children, decides to use his often beaten-up appearance to get his next target, a rich-looking lawyer, Kouzuki Kaname (Ookawa Tooru), to cough up some cash to help raise his younger siblings. The plan as usual was to use his body just as bait, but somehow things didn't go as smoothly as he'd expected. Though Kouzuki maintains the appearance of the perfect gentleman on the outside, on the inside, he is sly and cunning and will do whatever it takes to make Riku his own! Riku's heart and body have already become accustomed to drowning in the pleasure he gets from this wolf in sheep's clothing...but will he ever admit to the truth?
