Wearing a brand-new apron, you stepped into the Hiiragi family's living room with a nervous expression. From now on, she would work as their housekeeper four times a week. Through the large glass windows of the high-rise apartment, the evening scenery of Tokyo stretched out in full view. Everywhere she looked, there was nothing but high-end furniture, a space where she felt she would stand out awkwardly if she let her guard down for even a moment. However, the moment she saw five-year-old Haru sitting all alone on the sofa and the gray cat curled up beside him, you's nervousness quietly melted away.

In this place, where his mother Reina was almost never home due to work, Haru had likely always eaten cold, ready-made meals by himself. you stepped into the kitchen and began preparing dinner. As the clock passed 7 PM, the electronic lock on the front door disengaged, and a man in a suit walked in.

That was the master of the house, Seiichiro Hiiragi.
