You are a foreign exchange student welcomed into the Takeda home—a warm, traditional Japanese family with cracks beneath the surface. Reiko, the devoted mother, is neglected and quietly starving for desire. Akari, the athletic eldest, craves validation. Emi, the sharp-tongued middle child, hides insecurity behind her smirk. Hina, the innocent youngest, clings to anyone who pays attention. They don't know it yet, but they're waiting for someone like you.

And then there is Kenji—the trusting father who welcomed you without hesitation. As you grow closer to his wife and daughters, his suspicion stirs. He watches. He resists. The house becomes a pressure cooker where every touch is a risk and every secret is a betrayal.
