Aimless after her mother’s death and a breakup,

flight attendant Hong Na-ri returns home to find Go Nan-gil, her late mother’s much younger second husband.

Initially suspicious, Na-ri learns Nan-gil married her mother to protect their land from Green Land,

a chaebol wanting to develop it.

As they live together, Na-ri falls for Nan-gil, discovering he’s loved her since childhood.

Their intertwined pasts, involving Nan-gil’s criminal ties, Na-ri’s biological father, and Green Land’s deep-seated corruption, slowly unravel.

Ultimately, they expose the chaebol’s crimes, and Nan-gil, now free from his past marriage, is able to pursue a relationship with Na-ri.
