From Renta!:

Unstoppable force, meet immovable object. Suguru Shoji, an editor for a girls' manga publisher, is willing to do whatever it takes to rake in the sales; be it playing nice, wheedling, lying, blackmail...he's done it all. Yoichi Yanase, nicknamed "The Prince," is a bookstore employee famous for his good looks, great taste in comics, and being as stubborn as they come. When work brings the two together, sparks fly, and Suguru finds himself going head to head with Yoichi in a battle of wills. Will he get his way, or will Yoichi prove more resistant to his methods than he expected?
