At the tender age of a fresh college graduate, Na-eun suddenly finds herself raising her sister’s child, Ji-ho, all on her own.

Five years later, while working as a kindergarten teacher, she crosses paths with Kang-woo—the uncle of one of her students, Min-ho, who suffers from selective mutism.

Shocked to discover that Min-ho only opens up when he’s with Na-eun, Kang-woo makes her an unbelievable offer: become Min-ho’s live-in tutor for 30 million won a month!

Now, the two of them must navigate an unexpected “cohabitation” as they raise their children together.

Can Na-eun and Kang-woo heal the wounds in Min-ho’s heart and truly become a family?
The heart-fluttering journey of parenting first, romance later begins now! ♡
