Masayoshi Hayakawa (Joe Odagiri) is completely disturbed by the communal life with children. Meanwhile, Kosuke Miki (Yusuke Santamaria) brought a story about the release of a new song from a music distribution company. He is said to promise a CD release if there are many downloads, and justice that motivates him at all. Ahead of that, Riku Matsuno (Kanata Fujimoto)'s elementary school teacher (Hideto Iwai) contacted me to come to school because I had a consultation. Justice went out reluctantly, but the consultation was that Riku was skipping the practice of singing in the class after school. Justice that kicks back when it's crap. Riku headed to the park alone and started practicing singing in Dokan. Then he was witnessed by Hidezo Tokaibayashi (Tatsuya Fuji) who happened to pass by, and explained the reason why he couldn't sing the song on condition that he kept it secret from Mizuki Matsuno (Ayane Omori). He said he couldn't sing since his classmates laughed at him because his voice turned inside out in the very first practice.
Miki, who continues to work overtime every day, remembers having a tripartite meeting at the cram school on Sunday by email from his wife. Around the same time, Justice was working hard to write songs. Justice that immerses you in songwriting without seeing any time or surroundings. On the other hand, Mizuki hears from Ryota Hanamura (Muro Tsuyoshi) who met on the way home from school that Riku has not been practicing singing. In addition, Kokoro Osawa (Sugisaki Hana), who was asked by Hidezo to secretly monitor the land, and Yoko Aota (Shihori Kanjiya), who saw her heart, are being bullied by a boy's classmate in the park.
