The first thing Jeon Jeongguk noticed was the quiet.

It was a Wednesday afternoon, three weeks into the arrangement, and he stood in the doorway of his own home, a sanctuary of masculine, minimalist greys and blacks, and felt the unfamiliar sensation of peace.

The source of that peace was currently on his hands and knees in the living room, his back to Jeongguk, picking up scattered puzzle pieces.

Kim Taehyung.

Jeongguk's new nanny. His twenty-year-old nanny.

He'd been desperate. Sooya, his three-year-old daughter, his entire universe, had burned through three nannies in as many months.
