Dressed as an NPC, the System Forces Me to Destroy the Heroine

I dressed up as Ba Zongwen's NPC. Every time I want to lead the male protagonist to do something important, the woman will come over and steal him. 99 Times. I'm done. The system said: Your mission is to let her die. I said: You don't need to rush me. I have the final say when she goes offline. Just as I was about to take action, another NPC stopped me: "Don't even think about it. She must live. Her life belongs to me." I looked at her: "What a coincidence, I thought so too."
