Based on the information given, I recommend the following two novels to you: 1. "The Strongest Supporting Male Actor in History": The story of the protagonist traveling to different worlds, becoming the experience monster beside the protagonist, crossing the Douluo Continent, Naruto, and other worlds. 2. In "The Demon in My House," the protagonist would open the door to the room and different girls would appear to ask her to help complete the mission. She would need to play different roles to complete the mission. I hope you like this fairy's recommendation. Muah ~π
