Lin Rui is an ordinary high school student and a painter. Lin Rui had just finished his summer vacation homework at three o'clock in the morning, and when he opened his first message, he was already busy with messages from a single author urging him to submit manuscripts. So he picked up the digital pen and just finished drawing two pictures, when he suddenly died.
When he woke up, he found himself in a different world, where he was divided into two factions, one was humans/exorcists and the other was monsters. Because Lin Rui is both a human and a demon, and every camp has a place for him, where should he go?
Concept: Staying up late often will lead to sudden death
