Hitomi, who works as a cram school teacher after putting an end to her teacher life, was busy looking for housework help as she lived alone. One day, Yui, who was looking for a job when her husband was restructuring and sold her house, came to see her live-in housekeeper flyer. Her Yui's visit causes her Hitomi's reason to collapse, albeit fragile. Yui was exactly the same as her student, whom Hitomi secretly fell in love with when she was a teacher and parted ways with her after her death. Hitomi secretly sneaks into Yui's bedroom where Yui, who doesn't know anything about her, sleeps in a sweat.
