I think Dietrich is possessed by the third floor manager hence why he is uncomfortable with the 4th floor and I think he might be possessed because he has reached a certain level of corruption already maybe like a condition to be possessed by the 3rd floor manager, this might be a stretch but who knows. I just love how this story has me guessing or theorizing, hardly find stories that make me do this nowadays.
It's an omegaverse manhwas where the alpha childhood friend gets into an accident and ends up in the body of alpha his childhood friend married, I think he also regressed back to the start of their marriage, I can't remember what happened to his original body or the soul of the alpha his currently inhabiting
