Kyoko is a beautiful, bright, popular high school girl, but at home, she takes on a different look, dressing down and removing her makeup, tying her hair back, and doing housework while taking care of her little brother. She does not want her friends to see her in that state, but when Izumi Miyamura does, they agree to keep their real personas a secret. She begins to have romantic feelings towards Miyamura. She heard his confession to her when she had a cold and said she heard everything he said. They became a couple after she admits Izumi is her boyfriend when her father asked her when Izumi was present.
At school, Izumi appears to be a gloomy otaku fanboy with glasses and keeps to himself. However, outside of school, he is rather good looking and laid back, with a punk-styled look and nine piercings (four on each of his ears, and one on his lip), as well as tattoos. Despite his school appearance, he has only a casual interest in manga and has mediocre grades. His family runs a bakery. He accepted his lonely existence but upon learning that Kyoko does not mind how he looks, he slowly gained confidence and friends among his classmates. Unlike his gloomy image in school, Izumi’s look outside school would have easily gained him popularity with his pretty face that he hides under glasses. Izumi grows his hair long to hide his ear piercings, and wears long-sleeved shirts to cover his tattoos. He finds Kyoko’s real side to be cute, even when she gets angry. He was fine with being friends but his honest attitude allows him to tell Kyoko the things he admires in her. They officially became a couple after Kyoko’s dad asked Kyoko whether Izumi is her boyfriend.
