MC is extremely slow on understanding situations it's kinda frustrating to read

I think he knows what's going on at some scenes but he pretends he doesn't and just keeps acting clueless and it agitates the ghost even more

Duh.. if you were in his shoe you were gonna slow too. Even me I might got frustrated coz I can't really understand what's going on?.. actually i can't blame him if he gets crazy coz he was literally confused of the things he see and experience it.. it's like he was sitting in a roller coaster ride..

Nah, from what I remember he knows. He’s just in denial at it cause he’s scared shitless about ghosts
