Do Won

Do Won is the building manager of the villa (Later 'One Hotel') inherited by Baek Seju. She used to be a great swimmer athlete but she quit due to emotional matters. She's one of the main characters of WDTFS: One.

Appearance
Do Won has a thin, dark complexion but clearly developed as an athlete of her class. Her weight and height aren't known, but she's way taller than Seju (5 '6 ft) so she might be 5'8 ft. She has brown hair and hazel eyes, as well as a tiny mole above her left eyebrow and a sole earring in her left ear (A gift from Seju).

Personality
Won is a shy, protective, innocent yet mature person. She cares deeply about the ones who she loves, even sacrificing herself for their well being.

In WDTFS: One
After the main events in the story of WDTFS (And WDTFS: Paradise) Baek Seju travels to Jeju Island to take over the hotel that her mother used to manage in order to know more about her and since she 'didn't have anywhere else to go' now that she broke up with the love of her life and she was still dealing with Sung Sumin's ghost.

The current one in charge of the hotel's maintenance and management is Do Won, daughter of the couple who used to work with Seju's mother and now co-worker of the new president, who for a while didn't trust the brunette until the torturous silence of the place gave them enough reasons to share little things about them, drink, and deal with an atmosphere of sexual tension, at least from Seju's point of view. However, turns out that Won ends falling in love with the president while her true motives were protecting her as a request by Seju's brother: Baek Sehyun, a thing that it's revealed in the blossom of their relationship after an attack planned by one of Seju's oldest brothers and the suspicion he indulges on the president about the manager.

It's later that Won tries to save the relationship by telling Seju the truth, and then she helps the pink-haired with the solution for the pain Seju carried from her past relationship. It's also shown that Won tries to teach Seju how to swim, but the pink-haired just sucks at it.

In WDTFS: Will
Three years later, as the first snow falls, Do Won is on the phone with Seju who tells her that it's snowing, to which Do Won replies that it is the first snow of the year. She asks if Seju likes the snow and Seju replies that she does. As the snow continues to fall, Seju with a smile on her face, asks Do Won to come outside to watch the snow fall together.
