In order to save her family, the business girl Shen Zhezhi married into the prince's mansion to celebrate her happiness. Her husband, Yan Qingci, is a powerful Marquis of Dingbei and a well-known cold-faced King of Hell in the capital. He suffers from old wounds and has a gloomy personality. A contract stipulated that they would not interfere with each other for a period of three years. Shen Zhezhi originally just wanted to take advantage of the opportunity to take revenge, defeat the enemies who framed the Shen family, and make enough money to fly away. She calmly planned, opened up a business route in the backyard of the Hou Mansion, and made the business prosperous, but she didn't know that her every move had already fallen into those deep pool-like eyes. At first, Yan Qingci regarded her as another pawn to cling to the powerful, and watched with cold eyes, but gradually he discovered that this nominal lady was ruthless in scheming, and did not care about shortcomings, like a thorny rose, taking root in his desolate life. When he discovered that the enemy she secretly collected evidence to bring down was actually connected to the forces that plotted against him, everything began to get out of hand. He pressed forward step by step, and she retreated step by step. It wasn't until she handed over the letter of separation that Yan Qingci was shocked to realize that the thorn had already grown into the bone and blood, and peeling it off was like deboning.
