Tang Junyao, a surgeon, was forced by her grandfather to go on a hunger strike. She and Ji Hancheng, the richest man in the imperial capital, whom she had never met before, quickly obtained a certificate and agreed to divorce in three months in secret. After Grandpa Tang passed away, Tang Junyao moved into Ji's house and began living together with the cold and arrogant Ji Hancheng. At first Ji Hancheng believed that she was a scheming girl who was greedy for wealth and made things difficult for her at every turn. But Tang Junyao's independent and brave character and attitude of neither being humble nor overbearing gradually broke his prejudice. Her half-sister Tang Junting frequently instigated and framed her, and the doubts and difficulties raised by relatives of the Ji family were all resolved one by one by Tang Junyao. The two acted in a tit-for-tat confrontation, and Ji Hancheng was the first to change his mind from indifference and alienation to secret protection.
