At a young age, just after graduating from university, Na-eun suddenly finds herself raising her older sister’s child, Jiho.

Five years later, while working as a kindergarten teacher, she meets Kang-woo—the uncle of Minho, a child suffering from selective mutism who only speaks in front of her. Shocked by this, Kang-woo offers Na-eun a live-in tutor position with a generous monthly salary.

As they begin living together—not quite as a couple, but not quite apart—while caring for the children, their relationship slowly deepens.

Can Na-eun and Kang-woo heal Minho’s emotional wounds… and become a real family?
A heart-fluttering story where parenting comes first—and romance follows.
