Uso Kareshi demo Ii kara Tonikaku Shitai Mashiro-chan

Mashiro Naomoto wants to have a taste of romance and even get to try lewd things, now that she has become a high school student. However, she has low self-esteem and as a result of lacking confidence in herself, she began to think that it's probably impossible for her. Right at that moment, to her surprise a handsome male classmate named Oosagi-kun confesses to her. Mashiro starts to suspect that his confession must be some sort of punishment game, but her own desire to do lewd stuff wins over it and as a result, she does the opposite and makes a move on him... it's a case of sexual desire winning over suspicion?! This is a romcom where a high school girl's libido will run wild!! (Source: Flex Comix, translated)
