Thank you so much trying out the game!
You're not being stupid at all!
That was probably my least favorite element of the story too, so you're not alone there!
I had originally intended it to connect to the MC's original career, but I decided to keep the MC as a blank slate to focus on more on the story's themes. It's the one part of the game where I cringe a little when hear it (that, and the parts where I hear my own voice >w<). I realized that I should've left that part out and just let the souls help the MC without accidentally hinting at a 4th wall break, but by that point the game was out.
I decided to let it stay and be a lesson for myself for any future games I work on -- to more carefully consider whether or not what's written benefits the story.
Thank you for your honest comment! I'm glad you were still able to enjoy the actual ending!
