Delightful Girl, Choon Hyang (2005)

Ayaka, who works at the bridal department at a hotel, has a beauty that everyone recognizes, yet her personality is the worst. Everyone calls her a "wicked woman" after the way she wraps numerous men around her finger. The one who sets his eyes on her is the hotel's new executive Togo, who is the son of a very powerful person of the town. What are the orders that this King-like man requests of her!?

Both plots have the same framework: the lead male has a former love but because of some circumstances he has to be together with the lead female, then appears another guy.
Moreover, both dramas are written by Hong Sisters.

The way they struggle for their love is kinda similar to delightful girl, choon hyang. The emotion and feeling feel the same.

Both are older dramas that are worth watching if you enjoy romance. The couples have magnetic appeal that carries the shows.
