In order to save her family, she contracted marriage with Zhu Ma, who was five years younger. He thought it was a cold deal, but he didn't know that every detail was included in his calculations - the debt amount was her pocket money back then, there was always her favorite sugar-free yogurt in the refrigerator, and even the pen she proposed to was the one she casually lent to him twelve years ago. He has been waiting for 3,726 days for this paranoid secret love to be closed.
