I honestly loved the story, acting, and twists and turns in this show. The BTS on this were even more fun to watch. The 'Husband' is so wholesome in real life, and as much as the show makes you hate him, watching his interviews and the BTS of the show makes him much like Tom Felton for Harry Potter fans. They hate him as Malfoy but love him as a person.

Kang Ji Won with stage 4 cancer, and a best friend who can't live without her is dying. Her deadbeat of a husband isn't paying her medical, so she heads home, only to find her husband and best friend in bed, planning on how to spend the insurance money once she's dead.
She confronts them and, in the process, falls on a glass table, leading to her death. When she wakes up, it's 10 years earlier, and she has a second chance to forego all the bad. Her first lesson: What happened before still must happen. Her goal: Make her "Best Friend" marry her once-husband (who is currently her fiance/boyfriend? Honestly, I had trouble keeping this straight as she broke it off a few times at the start). Can she escape her fate of marrying a deadbeat cheater and find the happiness she deserves?

Yoo Ji Hyeok, her Chief Manager at work, starts to notice her, and their feelings grow. He starts to help her with her goals. He, too, has a secret.

I absolutely loved Kang Ji Won and Yoo Ji Hyeok together, and their chemistry was off the charts. His unwavering support of whatever she needed was heartbreaking to watch as he struggled with her plans, but it was heartwarming to know he trusted her reasons.

I fully recommend this as a watch albeit for older teens and adults, and not children.
