The first step to winning the Love Game is saying “I love you.” So how do you lose? By admitting you’re in love!

Let the games begin! Since childhood, Yukiya Asagi and Miku Sakura have played the Love Game, where they try to fluster each other with a simple “I love you.” But after falling in love for real and refusing to admit it, neither of them can afford to lose this battle!

At long last, Miku and Yukiya spend the night under one roof. Their last sleepover was years ago, and their relationship has changed since then. Under the pretense of the Love Game, they both make bold moves to test the limits of their physical intimacy. But just how far will they go to claim victory?
