I am Mita, Your Housekeeper.

A father of four, grieving the recent loss of his wife, hires a housekeeper from an agency, but the woman who shows up is not at all what he expected.

Keiichi asks Mita to keep what he said a secret from the kids, while Kaito asks Mita to deal with a bully at his school.

Yui hears the truth about her mother and doesn't take it well. She asks Mita to go to her father's office to find out more about the other woman.

They've left home, but the children disagree about what to do next. Yui has no intention of ever forgiving her father, but Kii wants to go home.

The children live in the house while their father stays in a business hotel. Kakeru takes his anger out on his basketball team.

Their grandfather insists on adopting the children, despite their objections. Urara tries to get Yui to talk things over with her grandfather.

Yui wants her father to come to Kii's preschool performance to prove that he still loves them, but Keiichi doesn't know what to do.

Keiichi and the children try to talk to Mita to learn more about her, but she refuses to speak to them about anything other than housework.

The Asudas try to find out where Mita's gone, only to find that she's now working for their neighbor. Urara tries to help out around the house.

Mita returns to the Asuda house, but she starts to see visions of her husband and son. Kaito has to write a letter to his mother for school.
