Nishina, Maya, Shiro, and Aoi are four good friends in their second year of high school with good looks but disappointing personalities. The four who decided that they will never fall in love, formed their own club, known as the "Muda-bu" (Useless Club), which focuses on researching silly themes and uploading them on social media. One day, they decided to do an experiment from a manga that says, "If you run with a piece of bread in your mouth and bump into someone, you will fall in love". While trying to conduct the experiment, they accidentally bumped into someone while having a piece of bread in the mouth.

Minato is a university student and has a fear of germs. She isn't interested in looking pretty. She lives with her stepbrother Toru, who is her stepbrother from her mother's remarriage. Meanwhile, Toru is handsome and a player with the ladies. He doesn't resist women who come on to him and he doesn't stop women from leaving him either. Minato is uncomfortable with Toru and his ways with women. They are the same age and attend the same university. They have an agreement, where Toru will not approach Minato within 2 meters when they are outside.
One day, due to her friend’s request, Minato puts on make-up and wears her friend’s high school uniform. While she is out walking in public, she happens to meet Toru. She unexpectedly lies to him about her identity and tells him that she is a high school student. Toru falls in love with her at first sight.
