A few key points:
First, in terms of articles: This is my first time writing an article. My writing may not be very good, and it is still very slow. Please forgive me. I'm happy to accept suggestions, but I can't accept some of the radical comments. Please forgive me, I'm sorry. .
Second, in terms of the protagonist: I don't think the heroine is a Mary Sue, but if you have anything else, please bring it up. Thank you for your cooperation. The heroine is sometimes unprincipled, but overall she's pretty normal, with both shortcomings and advantages.
Third, in terms of style: you can tell from the title - this is a time-travel article. My laugh point is a little low, but I will try my best to create some funny elements. There are a few chapters in the middle that may have speculative elements. If you have any questions please ask.
Fourth, in terms of supporting characters: mainly the characters in "Devil Lovers", there are also a few original characters. In addition, there is a possibility that there may be characters from other anime. Of course, this is all a story later.
Fifth, in terms of CP: at least the heroine has no CP.
............ Above. I hope everyone can take a look and give some suggestions. Thank you very much.
