Kujou Kiyosumi was a very awkward and nerdy individual during his youth. Despite this, he had the bravery to confess his love for a girl one day in elementary school. However, to his dismay, she publicly declared him "disgusting" to be around in front of the whole class. This left Kiyosumi shocked and seeking help to become more likable. He turned to Sagiya Maki, the coolest guy in the class, and began his training. By the time he reached high school, Kiyosumi had become popular, alongside Maki. However, everything was soon to change.
