Drunk Night Made Me Billionaire's Fake Wife

The Jiang and Shen families arranged a marriage to hold their business together, and the bride, Shen Zhiyi, is in prison for drunk driving, so the wedding cannot go ahead as agreed. Song Yanzhi had walked in on her boyfriend with a rich woman not long before that, drunk herself into the ground over it, and ended up in bed with Jiang Yancheng by mistake. He runs his family's company, keeps a cold face on it, and he is the groom the Shen match was for. What he puts to her is that she take Shen Zhiyi's name and stand in at the wedding so the two families keep their deal. She takes it, and whatever is between the two of them comes after the marriage.
