I Was the Heroine's Best Friend in the Novel and Had Sex with Her

I passed away due to an accident, and when I was dying, an angel brought me an opportunity to be reborn: I had to enter the world of 100 novels, and match up the conflicting male and female protagonists as the heroine's best friend. I could be reborn a hundred times, but I didn't mention who was praying. I traveled through campus, city, fairy tale and other novels, listening to the heroine's grievances and resolving misunderstandings. In each novel, there was a person with a completely different identity, face, and name who silently helped me: in the campus novel, the transfer student helped me find the apology letter hidden by the heroine; in the urban novel, the coffee shop owner reminded me of the hero's feelings; in the fairy tale novel, the casual cultivator helped me avoid the villain's trap. They always appear when I need them, and they also leave familiar objects such as cedar-flavored paper towels and childhood milk candies, which make me feel inexplicably close to each "him". This sense of familiarity gradually turned into goodwill, and eventually into love. I memorized the name and appearance of "him" in each novel, but after completing the task, I could only bid farewell to the current "him" and rush to the next world. It wasn't until the end of the 100th novel mission that the angel revealed the truth: the person praying was my childhood sweetheart Gu Ran. He entered every novel with me at the cost of being "indistinguishable from each other and disappearing if I violated the rules." He was also the helper with different faces. In the end, I was reborn with 100 memories of him and met him again in reality.
