Yūto visits Mika's junior high school—an all-girls' school—upon her invitation. Mika introduces him to the rest of the girls in her class. He was surprised to know that Mika was a popular girl at school. She is a class president and a school idol, pretty much like her sister Haruka. After their meeting, Yūto decides to go and see Mika's stage play. After the stage play, both Yūto and Mika are accidentally locked up in the stage room. Luckily in the end, Mika's maids find them.
