Mitsuo Ichikawa receives a phone call from Mitsuo Ichikawa. Their names are pronounced the same, but spelled differently using kanji. They also graduated from the same high school. Back in their high school days, Mitsuo Ichikawa was like a subordinate to Mitsuo Ichikawa. Mitsuo Ichikawa is now a hoodlum and tells the other Mitsuo that he killed a woman. They become accomplices and build a new relationship.
Rihito Sajo, an honor student with a perfect score on the entrance exam and Hikaru Kusakabe, in a band and popular among girls, would have never crossed paths. Until one day they started talking at the practice for their school’s upcoming chorus festival. After school, the two meet regularly, as Hikaru helps Rihito to improve his singing skills. While they listen to each other’s voice and harmonize, their hearts start to beat together.
