Iku Fukuda, the protagonist, was an ardent fan of working with children. Consequently, he applied for a job at a daycare center, which he was fortunate enough to get. However, the job's severe challenges and difficulties quickly overwhelmed him, prompting him to resign after only two short months. Despite this setback, Fukuda remained undeterred in his mission to instruct and nurture children.
Furthermore, in chapter 6, titled "Hoiku no Tamago," Fukuda teams up with Ishiyama Horo to provide a heartwarming story of their experiences working with children. Together, they share with the audience the joys, challenges, and struggles of working with youngsters, highlighting the importance of commitment, resilience, and teamwork in providing quality care to children. They also provide practical tips for parents and caregivers on how to handle children's misbehavior, helping children develop good habits and morals, and creating a nurturing and safe environment for them to grow up in.
