Renka Saeki, an alcoholic aunt who quit her job and spends her days drunk in a filthy, cluttered room. She sits lazily on the sofa with a beer in hand, awkwardly conversing with her nephew. Their conversation gradually deepens, drawing them closer while she remains heavily intoxicated. Trying to stir up old memories, she provocatively says, "You used to tell me you'd marry me when you grew up, remember?" Her eyes glisten from the alcohol, her gaze fixed on his chest as her hand reaches out to touch a body she shouldn't desire. He offers slight resistance, but the sensation is soon accepted. An awkward kiss, hands fumbling at his chest, and then he experiences pleasure for the first time. Drunkenness and guilt intertwine as his virginity is quietly taken. A secret between only the two of them creates a relationship that can never go back.
