Dr. Lisa Manoban is the most popular medical oncologist at the hospital, but not because of her work on breast cancer. Though she's a brilliant doctor, her nurses and patients can all attest to the fact that she's even better in bed. What she's got in her pants is the talk of the town. The only woman who doesn't seem to be smitten by her is Jennie Kim, the nurse with the plumpest bum and the perkiest bosom. After she lets her inhibitions loose during a night out with colleagues, things between the doctor and her nurse might never be the same.

Jennie Kim, the only daughter of Roger Kim, the president of the largest hospital in Gangnam and one of the top hospitals for medical care in South Korea, has yet to be dating a mysterious person from her father's blind date set-up. Uninterested, she walks out and met a heart surgeon, Lisa Manoban, the heart surgeon who wakes Jennie's carnal desires. Little did she know it's her blind date partner. Let's all witness how Jennie and Lisa work their steamy yet dreamy relationship!

They said there are only two things why past lovers are still friends. Either they are still in love, or they never were. But does that mean Jennie Kim and Lisa Manoban are still in love with each other? 1 week- 7 days in Jeju Island to sort everything out. Will they give each other a second chance? Or will they move on with somebody new and just stay friends? "She's my favorite ex, my favorite regret, and my best mistake. I don't think I can find someone like her again."
