My Home Mirano(1996)

My Home Mirano

Mirano Furata is a 20-year-old newly trained housekeeper. She is sent to live with the Kikuchi family with the father and his sons. But the father, who was the only adult, told her, "Take care of them," before going away on a long business trip. Shuntaro is just a baby, and Naoto, a junior in high school, hates women for some reason. In the Kikuchi family without a father, Mirano's struggle will begin.
