V or Kim Tae Hee or Velarie Kim, a cardiologist of Y Hospital. Well-known due to her geniuses and speed in surgery. Quiet and adores alone time. Socializing ain't her thing. She was an orphan yet being adopted by one of the most well known TV anchors, Mr. Kim. Ever since Mr. Kim passed away, V moved to live at the hospital dorm despite still having her stepmother and stepsister. She is a Cinderella in this modern era, but still grateful enough to have a stepsister who loves her despite being tortured by her stepmother. Due to her diligence in her work, she was offered a few times by other hospitals or being promoted to be the Head of Department, yet she refused it all over again. Cause being promoted means she needs to see lots of people, attending events with the rest of higher authorities and the least she would do is be on the same floor with her senior, or soon to be the next in line of Y Hospital Director, Bae In Hyuk.
Bae In Hyuk, a neurosurgeon, only son of Y Hospital Director, Bae Sam Hong, a grandson to ex-politician, Bae Sok Im. His family is still one of the most respected families in that town. Bae In Hyuk is known as the most devilish sunbae in his department. He is so cold, strict and arrogant. However, he is the warmest person. He just acted cold as he avoided attention, especially the hungry-medias. His forced marriage with V due to family relationship made him become the next person on the list that V hated the most.
The return of V's stepsister, Janice Kim or Kim So Hyun to the town after her disappearance 3 years ago, a day before her marriage with Bae In Hyuk is the turning point to Bae In Hyuk and V's marriage life. The news of her return is happiest news to V, but not to Bae In Hyuk. Even the secrets of those two families revealing one by one and V happen to learn about her origins as well.
