Female Lead Law

After I had a heart attack and died, I wore a book and was bound to a female matching system called Seventy-One. The task assigned to me is to be a matchmaker and match up the male and female protagonists. The reward is to send me back and give me a sound body. So what do I do now? I asked Seventy-One. Seventy-One spoke unhurriedly: First of all, you go to the mass grave to dig up someone. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
