When college freshman Riku moves into a quiet suburban house, he’s drawn to the warmth of the couple living next door. Their laughter fills the evenings, their smiles seem flawless — until one night, he sees what’s hidden behind their walls. The husband’s jealousy. The wife’s bruises. Unable to look away, Riku finds himself caught between compassion and desire, guilt and obsession. Each glance, each word shared with her blurs the line between right and wrong. As reality fractures, dreams begin to spill over — and the light that once felt comforting becomes a haunting signal he cannot escape.
