Everything was fine at first, you became good friends, you communicated well, you told him everything about him, but you had no idea he was leaking all the information to Phi Han-Wul, who told his father everything. His father came up with a cunning plan to marry you to his son.
When you found out about this, you refused, saying you wouldn't marry him! Then Min Hwan, your father, and Phi Han Ul went to your mother and forced her to sell you for 40 million won!
You came home and your mother said that they sold you and your father to the Pi family!
