After Being Bound to a Vicious Female Partner, I Make a Living by Doing Evil

Others bind the system to counterattack and cheat, but I bind the system to help the female partner harm others. Others gain experience by doing tasks, while I gain a debt of conscience by doing tasks. The Lord God said that completing the mission would give me wealth and freedom. I asked what the price would be, and he said that the heroine would die. I flipped the table on the spot: I'm not going to do this job anymore, I'll accept the separation of my soul, and I'm guaranteed to be the heroine!
