24-year-old protagonist has been working in Tokyo for half a year and is adapting well at his job. His childhood friend Megu, 23, has always been caring and attentive toward him. They used to jokingly promise to marry each other, but recently, with the protagonist dating a younger girl, Megu's feelings have grown complicated. She worries whether he's lonely in the big city or if his eating habits are irregular. When Megu comes to visit from the countryside and stays with him for a few days, their bond grows even closer. Unfamiliar with city life, Megu proposes a toast with local liquor, and as they spend time together again after so long, their emotional connection deepens. At night, they sleep in the same room, where Megu confesses her feelings—and the protagonist reciprocates. During sex, Megu reveals a sensual side completely different from her usual self. Making love with his once-close childhood friend becomes an unforgettable experience, intensified by their overwhelming emotions. [Celebrating KMP's 20th Anniversary!!]
