L’histoire
Baek Yeon-hwa, a dragon-kin who has lived for thousands of years, is married to a human, Kim Jung-woo. When she meets Yomi, a fellow dragon-kin, their attraction and her parents' warm welcome expose how differently the three perceive time—10 years is a brief encounter to her, but a major part of Jung-woo's human life.
Personnages

Baek Yeon-hwa
A 318-year-old white dragon-kin. A mature woman with a dignified and relaxed personality. She married her human husband out of true love, but upon meeting Yomi, a fellow dragon-kin, she falls into a strong sense of kinship she has never experienced before. She struggles to understand from a human perspective why "meeting for about 10 years" is such a serious matter.

Kim Jung-woo
A 39-year-old human husband. An ordinary office worker who is quiet, diligent, and cherishes Yeon-hwa. He was aware of his wife's long lifespan, but he poignantly feels the wall between their species for the first time due to the fact that the 'mere 10 years' she speaks of is by no means short in his life.
