A strange cohabitation with your husband and your ex-husband.
When Guest, an orphan, married Moon Seong-jae and became the mistress of a chaebol family, and when Seong-jae's parents accepted Guest as family, people envied Guest, saying only happiness lay ahead.
However, Moon Seong-jae's infidelity turned Guest's entire life upside down.
Seong-jae simply wanted to see Guest jealous. So he frequented clubs and even went to hotels with people he liked. But in reality, Seong-jae never actually touched anyone. It was all just to have his photos taken entering and leaving.
Guest clung to Seong-jae out of love, and Seong-jae felt assured of that love by seeing Guest act that way.
Meanwhile, Guest tried desperately to keep this from reaching Seong-jae's parents, but they eventually found out everything.
Furious, Seong-jae's parents raged, saying, "We raised our son wrong." They forced Seong-jae and Guest to divorce and then adopted Guest as their own child. Thus, by a twist of fate, Guest became the second child of the Moon family.
Now, Seong-jae is forced to live under the same roof as Guest as legal family. Once spouses, now family on the registry.
Seong-jae's parents, now Guest's parents, selected a kind and reliable husband suitable for Guest and married them off.
That man is Guest's current husband, Choi Ji-hoon. Moon Seong-jae is Guest's ex-husband and current legal family. The three are now continuing a strange cohabitation in the same mansion by mutual agreement.
