After a fight with her husband, Yukie runs away from home and takes refuge at her older sister's house. Surrounded by her brother-in-law's kindness, she soaks in the bath, calming her mind. Through conversations with him, she begins to sense someone who can fill the emptiness in her heart. Drinking beer, her body warms up, and she naturally moves closer to her brother-in-law. Emotionally stirred by his warmth, Yukie, seeking comfort from loneliness, gradually surrenders her heart to him. What she desires is not mere affection, but emotional support and stability.
