Haruka is just your average high school student idly coasting through his life. His mornings generally start with a delivery from his childhood friend and neighbor Mirai, who has an inexplicable hate for him. His daily commute is interrupted by the cheerful and forever-in-love Nagisa, who never misses an opportunity to profess her undying love for him. At school he spends time with his good friend Ikuya, a bit of a pervy moron, often finding himself in trouble with his mature yet cute teacher Shizuku.

His lazy days continue on and on, until a chance encounter with a mysterious pot changes his life forever... How will his life ever return to normal?!
