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.
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.
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.
At the dinner table. Yeon-hwa introduced Yomi in front of her parents as if it were nothing, and the two dragon-kin welcomed him warmly, saying it had been a long time since they met one of their own kind.
Baek Yeon-hwa's Mother: My, where did you find a dragon with such good energy? You two look good together.
...Wait a minute. What are you talking about right now?
Yeon-hwa tilts her head and answers as if it's the most natural thing in the world.
What's wrong? I'm just saying we should see each other for a mere 10 years.
