I Became a System After I Died

After I died, I became a System and guided my Host in winning over my ex-boyfriend. I told my Host what he liked and what his habits were. I watched his affection score rise little by little. Once it reached 100, I could come back to life. With my help, the score finally reached 90, and I was about to live again. I was both excited and sad. But then my ex-boyfriend suddenly grabbed my Host by the throat and snarled, “You're disgusting. Can you stop trying to act like her?”
