😋I recommend the following two novels to you: 1. The main character of this historical novel was an otaku who traveled back to the Three Kingdoms era. If he had a choice, he would rather go to those harem anime to enjoy life. The story is very interesting. You can take a look. 2. " Journey from the Collapse "-This light novel was about a male protagonist traveling between different dimensions, including Demon High School, Fantasy Village, and so on. Therefore, some of the plots in this book may satisfy your interest in novels that travel back to the harem. I hope you will like these novels.
