Li Ying lost her parents in childhood and was adopted by the Mu family. Because Mu Hechuan held hands and promised to "cover you for the rest of your life", she began a secret love for sixteen years, but it ended without any illness. His younger brother was admitted to the ICU to save someone, and Li Ying had to become Cheng Jingxu's contract lover to raise medical expenses. After the death of his younger brother, Li Ying was grateful to Cheng Jingxu for taking care of him for half a year and agreed to marry him. Little did he know that Cheng Jingxu had already fallen in love with her at first sight, and the half-seduce, half-deceive marriage was his long-planned sincere plan. After the marriage, Cheng Jingxu doted on her even more wholeheartedly, gradually melting her frozen heart. Faced with Mu Hechuan's regretful pursuit of love, Li Ying firmly chooses Cheng Jingxu and embraces his sincerity that has never been lost. Adapted from the Tomato novel "Bite Marks on a Foggy Night" by [Jin Miao].
