The most uncomfortable time travel in the world occurred at the moment when I stabbed the young male protagonist with a knife.
There was a blood feud at the beginning, and it was never cleared up. It was not a misunderstanding. The original person clearly killed the male protagonist and his whole family.
The heroine said in her heart, "It's cool. I have to treat the hero with all my heart and soul, and then deepen the sadomasochistic relationship."
The story of a false demonic witch and a poor righteous orphan.
(No spoilers, the plot is this, but in fact the main line of the story is not this at all)
