She doesn't want to go through that again, but she doesn't know what to do... In front of the agonizing Nonomi, a man named Masami appears, who chills the room with his unique communication style. Nonomi was excited, thinking, “Isn't Masami exactly what I should be aiming for?" But then her ex-boyfriend shows up...? This is a love-study comedy between a gyaru with a lot of romantic experience and an unpopular virgin! (Source: DRUNK!, translated)
