Reborn in the 70s, I Made My Brother's Slanderers Regret

In my last life, I took pity on a young woman who was returning from rural work service and let her stay at our home.

The next morning, Katherine Harding stood there clutching the red camisole at her chest, sobbing that my brother had crept into her room in the middle of the night.

My brother had no way to defend himself. He could only marry her.

Not long after, I married my childhood friend, the boy I'd grown up with.

I never expected that after the wedding his whole nature would change, and the two of us would torment each other for the rest of our lives.
