You Suck at Love!

"If I win, I get to do whatever I want to you, right?"
Shou spends his days on the receiving end of his very intense father's wrath. Shou lets out his pent-up frustrations at a bar, with a little game. What kind of game, you say? The salacious kind -- the man who outdrinks the rest gets to spend the night with Shou. However, one day, a mysterious man named Ichijo disrupts Shou's game and even goes as far as to lecture him on it! What happens when an irritated Shou tries to give Ichijo a piece of his mind...?! A clumsy love story between an unfriendly hottie and the heir to a traditional inn!
