Anzu Murata (Mei Nagano) applies as housekeeper for the wealthy Miratai family that owns a hospital. Unknown to the mistress of the house, celebrity homemaker Makiko Mitarai (Ren Hanami), Anzu is her estranged stepdaughter who is trying to find out who burned her family's house down 13 years ago.
Back then, Anzu lived with her father Osamu Mitarai (Mitsuhiro Oikawa), mother Satsuki (Elyse Dinh) and younger sister Yuzu (Yuri Tsunematsu) happily and luxuriously in a mansion.
While their house was mysteriously engulfed in flames, Anzu saw Makiko, her mother's friend, among the bystanders, smiling triumphantly as she watched the house burning. Anzu therefore harbored suspicions about the tragic event.
Satsuki became depressed with guilt about being the culprit, thinking she left a stove on and caused the fire. At the same time, Makiko became close to Osamu, comforting him as needed. Eventually, Osamu and Satsuki divorced. Osamu married Makiko and abandoned his children. Satsuki developed amnesia and has been bedridden in a hospital. Anzu believes that her mother's guilt caused her health problems and that an apology from the real culprit would heal her.
This is an interesting watch. There is twist after twist towards the end that leaves one feeling breathless at the ride the writer takes viewers on. The romantic angles are not bad, either.
