I Transmigrated into a Book as the Female-Led Novel’s Second Male Lead, but He’s Far Too Rational

Ding Li wakes up to discover he's transmigrated into a book aimed at female readers, and become the second male lead who willingly acts as the heroine's knight, even going so far as to go bankrupt and end up in prison for her!

All he wants to say is this: Male and female leads, your happy life built on sucking me dry is over.

Years later, after making a name for himself and reaching the pinnacle, he looks back to find that the original novel's leads have become laughingstocks whom everyone loves to hate...!
