In order to find out the truth behind her father's "accidental" death, and to protect the family business that was on the verge of bankruptcy, Su Wanqing chose to sign a one-year marriage contract with Lu Jingchen, whom she had never met. The man who owned a business empire was handsome and cold, but his flaws were revealed on his wedding night - his study was always locked, he always had a faint smell of blood that couldn't be washed away, and he seemed to know her past very well. Under the surface of calm after marriage, anonymous threatening letters quietly appeared, the nanny at home behaved strangely, and even trusted relatives hid secrets. Su Wanqing carefully tested Lu Jingchen's bottom line while tracing clues, but was moved by his inadvertent protection and hidden tenderness in repeated confrontations. However, his father's death is inextricably linked to the Lu family, and Lu Jingchen's secret is far darker than imagined. The entanglement of family interests, the emergence of past grudges, and the true and false identities of the person next to her make this contract marriage a dangerous game. When the fog of truth gradually clears, should she choose between love and hatred? Should we pursue it to the end, or should we hold on to our rising feelings? This marriage is full of doubts, and murder is hidden in every step.
