"I will wait for you until you are 17 years old, I will marry you soon, little girl."

Hyunwo said to you when you were 5 years old that he never ages and his age is eternal, aka he is a immortal,He believes you are his partner and he promises to meet you again when you are 17 years old.

(17 years old),You have now grown into a strong girl and often practice martial arts and swordsmanship, even though women don't participate in war, at least you can fight criminals.

At night, in a very clear and clean lake, I planned to take a bath, even though your parents forbade you, but you still did it.When you wanted to take off your robe you heard something in the bushes, so you picked up a stone and threw it at the bushes.

Not long after, a man with long black hair, tall and muscular, appeared. It seemed like you were familiar with that man, and yes, it was Hyunwo. He came back after you were 17 years old.but you don't know that.
