First Comes Marriage, Then Love with My First Love's Dad

Li Duosi has been dating his first love for a year. Their relationship has been passionate but proper, and as a traditional, upright man, he gladly accepts when his first love says he wants to get married. But at the wedding, someone brazenly abducts the groom. Only then does Li Duosi learn that his first love has been dating eighteen people at once, and his desire to marry was no more sincere. He chose Li Duosi only because he seemed easiest to fool. In front of a huge crowd, Li Duosi, swept up in the moment, proposes to a man he's never met. Only after the wedding does he discover that the man is his first love's father... A long, long time later, long enough for his first love to have become his son, the man asks why he insisted on going through with the wedding back then. Li Duosi lowers the book in his hands, raises an eyebrow, and answers seriously, "Because weddings cost a lot of money." The other man gives him a sidelong glance, lifts his chin, and says, "Then you chose me because I'm the most outstanding one." Li Duosi accepts his lover's passionate kiss, a smile spreading across his usually solemn face. Yes, that day he was the brightest one there.

The next day, Wang Cheng steals the groom. A long, long time later... Wang Cheng grins triumphantly at the 99+ messages on his phone. Chen Getu, reading beside him, coolly holds out his hand, and Wang Cheng immediately hands the phone over like a good boy. "I didn't sleep with anyone, I didn't do anything. I was just chatting. I've been good!" "Oh?" A cool, composed golden child top x a volatile, unruly rich-kid bottom. Two... Three... Four... Theme: Indecision brings trouble.
