Ryota, a middle schooler, has taken on the responsibility of raising his preschool-aged brother, Ai, following the death of their mother. Struggling with the overwhelming burden of household chores and childcare, Ryota sacrifices his own needs and dreams to care for his brother. As the days wear on, his frustration and exhaustion grow, and he begins to resent the younger sibling who clings to him incessantly. That resentment soon festers into something darker—hatred, and eventually, murderous thoughts. Under the crushing weight of childcare stress, Ryota’s mind starts to unravel. But is it truly Ryota who’s breaking down… or is there something deeper, something unseen, fracturing their world? A harrowing exploration of familial bonds, sacrifice, and the fragile line between love and madness.
