Yurika is a housewife with a husband and son. She was asked by her nurse sister to take care of her nephew Shun's dinner on nights she works, so Shun started coming to Yurika's house often... Her nephew, whom she hadn't seen in a while, still had the same bratty attitude from his childhood and combined it with reliable manliness. Yuri sees the figure of someone eating homemade food deliciously or feigning behavior, and feelings other than motherhood sprout. Then on the night her husband's infidelity is discovered, Shun worries about Yuri, and they end up crossing the line.
