Mai sees her husband off at the door as he heads to work again today. Living the quiet, obedient life of a married woman, her routine takes an unexpected turn when, on her way back, a young man from the same apartment building suddenly appears. Just as her husband leaves, the young man blocks her path. A tense atmosphere begins to fill the space between them. Mai feels uneasy, yet she's acutely aware of his gaze. Suddenly, a hand reaches out from behind, groping her back. His hands tightly grab the plump, denim-covered cheeks of her ass, squeezing them as if they might spill out. Trembling, Mai ceases resistance. Though she laments her helplessness, this encounter was no accident—it was carefully orchestrated by the young man. What changes will this act bring to Mai's heart? The drama that unfolds from this moment begins now.
