Despairing Pact: Forbidden Horror Tales Are Underway

This book is so uncomfortable to read. The protagonist is cowardly, timid, and breaks down too easily. He is always scared to the point of missing key clues or directly failing the copy. The protagonist hesitates to do anything and looks very frustrated. It is a poisonous point for me. And the protagonist is very holy. If the protagonist hadn't been the protagonist, and had that jade pendant, he would have died long ago, and he would always be a mechanical deity. For example, the uncle of the girl who had the surgery turned into an earthly Rakshasa. Why was it not mentioned at all?
