Once you enter the yandere, you are as deep as the sea. By the way, this is a story of time-travel and anti-travel. In the end, the male and female protagonists have to go back to where they came from, so this book is also called - Harming You Across Thousands of Years, eh!
PS. The yandere in this article is neither the female protagonist nor the male protagonist. Of course, it was originally set to be the male protagonist, but later I found out that the male protagonist became a good boy after it was written. Of course, it is clear who the yandere is in the article, so it is not off-topic. Please give me a pat. The author is a graduating student, so the update time is uncertain, but I will definitely not abandon it. Finally, this is my first long article, so please give me your advice.
