Happy Lesson

Fifteen-year-old Hitotose Chitose leaves the orphanage and returns to his empty childhood home, feeling isolated and lost. His life takes an unexpected turn when five of his female high school teachers decide to move in with him, becoming his new "mothers." Though their constant care and chaotic presence overwhelm him at first, their affection gradually teaches him the warmth of family and the joy of simple moments together. Each of his new guardians brings something unique into his life: a creative cosplay-loving teacher, a gentle homeroom mother figure, a loud and energetic sports enthusiast, a sword-wielding shrine maiden who serves as the school nurse, and a reserved, slightly eccentric science teacher. Together, these five women not only embrace Chitose but also welcome his two sisters into their makeshift family.
