After I Died, All My Love Interests Went Mad

After I transmigrated into a novel where everyone doted on the heroine, I became the villainous male supporting character. Then the System appeared.

She said that if I could win over any one of the heroines, I could return to my original world with a healthy body.

But I failed to win over any of them.

The fake heiress, who had grown up alongside me.

The real heiress, my unruly, boxing-loving deskmate in high school.

And the genius surgeon who'd been my childhood sweetheart.

Even my own daughter.

Without exception, they all fell for that poor, self-reliant boy and despised me.

The System sighed and said that if I could die at the hands of any one of the heroines, she would send me back to my original world.

Later, I tried everything I could until they finally killed me with their own hands.

But why had they gone mad?
