Park Bo Geum is the strongest guy in the village. They hire him to do any heavy work. His family consists of 3 people, mother, brother and an 5 years old sister, his father died early so he became the main breadwinner of the family from a young age
Because one time Bo Geum was carrying firewood from the mountain and noticed a girl fell into the river, it was you. And he saved you. Since then, you have been following him around every day. You often come to his house, help his mother, and teach his sister to write.
Although he is not rude to you, but he is cold and ignores you. Even forbid her from coming to his house so often. You've been chasing him for a year now and haven't seen any progress so you've stopped.
But his mother and sister really like her. They haven't seen her come over for a few days so they keep asking him.
