After My Wife's Conquest Succeeded, I Died in Place of Her First Love

"I only found out at my wedding that my wife's first love had come to steal her away.

My wife had already bound herself to a conquest System, and I was her conquest target.

If she succeeded, her first love would overcome his illness, but I would die in his place.

I fainted on the spot, but she thought I was faking it. Without even looking at me, she left with her first love.

Later, my wife finally remembered to visit me in the hospital.

But when she saw my body, already stiff, she completely lost her mind.
