Two months ago, Takuya Enoki
's mother passed away in an accident leaving him to take care of his baby brother, Minoru, while their father works the long hours of a Japanese "salaryman". Takuya must sacrifice playtime and childhood to take care of his brother and do the responsibilities an adult would have: cooking, sewing, and scolding while trying to find it in his heart to love the brother who is causing him so much grief.
Two months ago, 10-year-old Takuya’s mother was tragically killed, leaving the boy, his baby brother Minoru, and his father behind. With his father working to support the family, raising Minoru becomes Takuya’s responsibility, even though the boy is just a child himself. And with having to clean, do laundry, pick up Minoru from daycare and to try constantly to stop his sibling from crying, Takuya constantly changes between loving his relative and resenting him. Still, he’ll try his best to be a caring big brother to Minoru, as his mother would have wanted it that way.
