My Wish Makes Him Suffer Twice

The wish system has one rule attached to it. Whatever it grants, the man on the other end of it receives double. Lin Beifan wakes up inside a story as a disposable villain, the kind written in so the protagonist can take everything off him, and the system binds to him with Xiao Chen as that other end. So he wishes backwards. He asks for things whose doubled version arrives on Xiao Chen as a weight rather than a gift, and each one takes something off the standing that makes Xiao Chen the story's protagonist. He pulls apart the schemes Xiao Chen is running and breaks up the people around him. Song Yuqing is engaged to Lin Beifan, and over the course of this the two of them come to feel something for each other. Others start siding with him as well, which is not how the story was written.
