In order to treat my brother's illness, I signed a contract and became Fu Shiyan's "surface lover". He gave me supreme glory, but he was stingy with a trace of sincerity; he was so gentle to me, but turned around and waited all night for another woman. I thought it was just a simple substitute relationship until I accidentally discovered his encrypted photo album - it was full of photos of Su Qingyan, from a young student in school to an elite in the workplace, spanning ten years. It turns out that the underground love affair between Fu Shiyan and Su Qingyan has been deeply rooted in the bone marrow, and I, the "rightful owner" on the surface, is just a shield for their relationship and a victim of the Fu family's marriage. The wealthy family is as deep as the sea. Fu Shiyan's every step of the way, Su Qingyan's secret provocation, and the family elders' eager eyes made it difficult for me to move forward in this triangular entanglement. When the identity of the stand-in is exposed in public, and when I see clearly that there is no trace of me in his eyes, can I still stick to my original intention and find a way out in a desperate situation?
