I transmigrated into a novel I wrote and became the key supporting character who's supposed to drive the two leads together (as the female lead's best friend)! Instead, I make up my mind to become the biggest obstacle to their relationship. However, all of my plans were ruined by a mysterious transfer student. Do NPCs these days come with a built-in plot accuracy feature? On top of it all, my best friend has started shipping me with the male lead. Seriously girl, wake up — you are the female lead of this novel!
