Choose Me and Avoid Cat-Astrophe

Sabi, a member of the pussycat race of cat people, works as a waiter at a cat café. His constant attitude toward customers has been causing trouble for the café's owner, and he gives Sabi an ultimatum: "If you don't increase your sales this month, you're fired." To avoid that, Sabi has to bank on more orders off the café's secret menu that provides more "adult" services to trusted regulars. That, however, is a struggle for him... until Hazama, a newer regular, tells Sabi that he'll order him. Turns out, it's to propose a deal that Sabi has little choice but to accept. Even though he thought being with Hazama would be unpleasant, it ends up being the best he's ever had...!
