Shitenasasou de, Shiteiru Kanojo no Shiteinai Koto ~Kimi no Hajimete ni Natte Yaru~

"If you like me that much, that makes me happy. Are you sure you like me?" Rikuto Hikuma has successfully started a relationship with Nanami Nishigasaki. But he discovers that Nanami has had sex in the past. It not being her first time is quite a shock to Rikuto, who did not think that she was not a virgin. After all, you would think that someone focused on their craft would not be interested in romance or any other kind of activity. Rikuto's heart is somewhat shaken, and he is annoyed. It didn't take him long to realize that it was “jealousy”. "I want Nanami's first time, no matter what it is" Nanami who has already experienced sex must now experience something that she has not yet done. Thus began Rikuto's search for her “first time".
