Motokare 100-nin Ieru kana

At a mixer, 24-year-old Shinomiya Nonomi was worried. Yes, she is too popular with men... She has always been strangely popular, but because of that, she has experienced pain in the past. 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!
