A chance encounter at a local park sets the stage for an unexpected and intense romantic connection. While passing through on the way home from school, a student discovers a beautiful woman named Miu sitting alone on a bench, bearing mysterious bruises on her face. Driven by a mix of curiosity and concern, the student approaches her later that evening at a convenience store, offering a bottle of liquor as a gesture of kindness. To his surprise, Miu readily accepts the invitation to return to his home, signaling the beginning of an intimate and transformative night together.
As the night unfolds, Miu takes the initiative, framing her seductive advances as a way to pay for her stay. Despite knowing nothing about her background, the student finds himself deeply drawn to her, unable to ignore the vulnerability behind her striking beauty. They spend several days in a whirlwind of passion, sharing a private world that feels disconnected from the harsh realities waiting outside his apartment door. The chemistry between them is palpable, turning a simple act of hospitality into a profound, albeit temporary, emotional and physical bond that neither of them anticipated.
The reality of Miu’s situation eventually surfaces when she suddenly disappears from the student's life. It is revealed that she had been fleeing an abusive relationship with a man living in the same building, a situation that forced her to prioritize her safety over their brief romance. Fearing that her past would bring unwanted trouble to the student, Miu chooses to leave and return to her hometown in Fukuoka. This poignant story captures the bittersweet nature of fleeting encounters, leaving viewers to reflect on the brief but impactful connections formed in the most unlikely of circumstances.
