Heal My Heart

What do you do when the person you're secretly in love with marries your best friend? For Umji, the answer has always been simple: stay loyal to Yujin, love her children as her own, and bury her true feelings for Yujin's husband, Wonwoo.

Wonwoo's career as a high-fashion model constantly takes him abroad for long photoshoots and runway schedules, making it easier for Umji to keep her distance-until sudden tragedy shatters their lives.

When Yujin, pregnant with her fourth child, dies in a tragic car accident, her newborn son miraculously survives. Devastated, Umji upends her entire existence to step in and help co-parent the grieving children alongside Wonwoo.

On the one-year anniversary of Yujin's passing, grief and emotional exhaustion overflow, leading Umji and Wonwoo to seek solace in each other for a single night-a decision that leaves both consumed by intense regret and lingering guilt. Wonwoo, who spent a full year drowned in anger, is now tormented by guilt for sleeping with his late wife's best friend... and for realizing he actually reciprocates her feelings. Though Umji's deep understanding of him used to scare him away, their shared tragedy entwines their lives closer than ever.

When Wonwoo leaves again for a major five-month international modeling contract, Umji is left behind to navigate the heavy weight of raising the children on her own. Though Wonwoo tries to remain loving and supportive from thousands of miles away, his eventual homecoming brings a shocking betrayal Umji never anticipated. Caught between lingering grief and complex devotion, Umji must finally stand her ground and fight for the future she truly deserves-whether Wonwoo is by her side or not.
