Pinecone's Questions (2)

The ML is psycho, and the FL comes from a modern world. There is another guy, and he is also from the modern world. They are trying to go back to their world when they both come to find they are from the modern world.However, the story starts with a story that the male lead actually kills the FL because she was boring. So the FL, who transitioned to this world, was actually reading the story, so she knows. So in order not to be dead, she tries not to be scared and boring, and tries to entertain the ML, saying she will open a winter hunting game. In the game, she is the prey and needs to protect herself from others who are after her. But they start falling in love with each other. However, the FL is really scared of the ML, and the ML is obsessed with her. So when he is on the journey to conquer the side country, she flees to a church with the guy who came from her world to go back to her world. However, she finds she is the saint and the actual saint who is supposed to have fallen in love with the ML is no longer a saint and actually in love with the guy who is also from the Morden world. And when the ML finds that she ran away, he chases after her to bring her back and tries to destroy the church. And the FL finds she needs to kill the ML to go back to her world. But when she tried to kill him, he won't die.
Ps: I know this story doesn't make sense. Also, for more information, the FL has pink hair and the ML has yellow hair.
