The adopted daughter of a wealthy family who was considered a fake, in order to repay the kindness of raising her, agreed to a business marriage with his childhood sweetheart, Lu Chaoyang, the heir to the Lu family, and became his substitute for Bai Yueguang. I maintained my final dignity with my coldness, while he used the heat of the sun as a gentle trap. We are plunged into a sadomasochistic relationship full of sweetness and torture. When the real wealthy daughter returned, I left the scene sadly, but unexpectedly exposed a shocking conspiracy about my life. It turned out that I was the real daughter who was maliciously exchanged, and the driving force behind all the tragedies was actually the "rightful owner" I had faced with guilt and the gradually darkening guardian behind her. Under Lu Chaoyang's paranoid redemption and the cruel impact of the truth, I must complete the counterattack from "substitute" to "protagonist" amidst family hatred, old love entanglements and self-salvation.
