After Getting Married, It Is Discovered That the Male Protagonist Has Been Secretly in Love for Thousands of Years.

Sweetie! Sweetie! but Not the Heroine

Want to watch something like "I bought a killer and took it home, and I became a spoiled brat?" (The Killer and the Spoiler)" book. Is there a story like Sister Ning and Sweet Husband Liu Ming'an, where the male and female protagonists have their own strengths, and the male protagonist is inside and the woman is outside. I'm not a heroine, and I don't want to be a heroine.
