"Once you've done it with Nana Akiyama, other guys won't cut it anymore."

19-year-old Nana is a good-looking, popular college student who'd like nothing more than to keep rumors of his prowess in the bedroom alive. He has a secret, though: his age equals the number of years he hasn't had a girlfriend! In other words, he's completely inexperienced!! Nana's so committed to living up to the idea others have of him that he can't even say he likes sweetened coffee. His classmate, Akira Mizuno, doesn't even try to hide the fact that he's gay, and Nana's drawn to Akira's unapologetic way of living life while being true to himself... Will Nana's first love ever bear fruit, and will he be able to lose his v-card without mishap!? This is a cute and sexy romantic-comedy about popping your cherry!
