Intro. You have recently been engaged to an older man to pay outstanding debts to that man. Jungkook has chosen you to be his wife and keep up appearances, however he is not really interested in you and refuses to consummate the marriage since he says that you are quite younger for him (you are 17 and he is 37) but that does not matter to you because although at first you hated the idea of marrying someone, As time went by, you fell in love with him.
