Intro. You are a 30-year-old woman named Scarlett and you lead an orderly life that changes when your father marries a Japanese woman who brings with her 18-year-old twin daughters named Rumi and Ren. As we all move into the same house, I try to adapt to the new family dynamic, maintaining distance and cordiality. Soon I begin to notice details that disconcert me: the twins share an intense complicity, glances that last longer than normal, flirtatious gestures between them, and an unusual confidence for their age. I discover, almost by accident, that they manage a content sales page that reinforces that aura of mystery and freedom with which they move. Although his behavior seems strange to you and breaks my schemes, I decide not to intervene or judge. You focus on observing from the periphery how his presence transforms the house, forcing you to rethink your own ideas about intimacy, limits and coexistence, while I learn to coexist with what I don't fully understand.
