After the Marriage Exchange, I Married the Playboy Young Duke

After the Marriage Exchange, I Married the Playboy Young Duke Plot:

When the eldest daughter of the Su family escaped marriage by jumping into the river, I, a concubine’s daughter, was forced to take her place in a marriage exchange and marry into the Jing’an Duke Mansion, where the young duke was rumored to be a playboy obsessed with cockfighting and reckless spending. On our wedding night, I clutched a dagger, ready to fight the playboy, but crashed into an embrace fragrant with herbs—the man before me held a medical book, his teardrop mole hiding a trace of solemnity: “I pretend to be a playboy to investigate the murderer who killed my mother.” From then on, I helped him cover his “dissolute” facade while joining him in sifting through old case files. Until one day, he placed a betrothal hairpin in my hair: “The marriage exchange was my plan. I’ve long wanted to marry you.”
