I have an idea that I don’t think has been done. A yandere who is dating an MC but MC messes up one day and ends up being killed by his yandere girlfriend. However, instead of ending up dead, he finds himself waking up, still very much alive. Why? Well, through some unexplained reason, he is trapped in a time loop and he is the only one who knows about it. Yet every time he dies, he still retains his memories of before. The only way he can get out of this time loop, in the MC’s opinion, is by trying to get her to stop being such a yandere. However, over time MC realizes maybe it’s he who needs to change.
