"Are you still playing that game...?" Harumi juggles housework and caring for her 8-month-old daughter, Miyu, while her husband, Takashi, spends all his free time glued to his games. Insensitive to Harumi's struggles, he brushes off her concerns. "You're sick? Don't give it to me. I have to go to work, you know." When Takashi prioritizes his game over her declining health, Harumi reaches her breaking point. Though he loves their daughter, he remains oblivious to the effort it takes to raise her. Frustrated and with nowhere else to turn, Harumi confides in a friend, who recommends a "legendary babysitter" with a reputation for solving even the most complicated problems mothers face. On a whim, Harumi hires him, only to be completely taken aback when he arrives. He's nothing like what she imagined.
