Having Sex Doesn't Mean Love.

"Your straightforward love hurts."

On a solo trip to Paris to relieve his broken heart, Genta meets a beautiful older man named Kamisaka. As they spend time together, Genta is charmed by him, and on their final night, a sweet invitation incites him to embrace him fiercely. Kamisaka treats him as a one-night stand, and Genta is about to give up when they reunite at university after returning to their home country. After boldly confessing to him, Kamisaka says, "It's all right if we're sex friends," and kisses him?! A platonic love that begins with the body.
