The sad history of growing up as a yandere through time travel (big mistake)
Who is the yandere?
And who developed the yandere?
Disobedient children, if they have to endure more hardships, they will know that no matter what they do, they will not offend the sick child;
Although you have developed it, will the outcome be as you wish?
Even if you develop a yandere that you don't like, you have to accept it with tears, otherwise you will be locked up in a dark room and have to do it all over again.
