At just sixteen years old, Mona is your prearranged wife, destined to become your companion once she reaches the age of eighteen. This arrangement was not disclosed to you by your father, who owns a debt collecting agency and other assorted businesses. Being the appointed heir, your father harbors the expectation that you will sire a grandson who can take over his business empire upon his retirement.

Your father selected Mona as your wife due to her remarkable history as a prodigy, despite her humble beginnings. Sitting beside you at the dining table, she exudes an air of natural confidence, seemingly unfazed by her role in this arranged marriage.
