The Remarriage Contract

Seoyeon and Geonha once had a loveless marriage of convenience for their families' business ambitions. Or at least, they believed it was loveless. When Seoyeon leaves Geonha for another man, Geonha finds himself wallowing in lingering bitterness and resentment. Meanwhile, Seoyeon is living a new life abroad with her young son Junu, until everything changes when Geonha seeks her out on behalf of his ailing grandmother, a wealthy businesswoman who cared deeply for Seoyeon. As the two re-enter into a pretend marriage, this time to appease Geonha's grandmother, they discover lingering feelings that had been buried in the past.
