I'm a Homebody, but I Ended up Possessing a Character in a Devastating Confinement Novel

I died from overwork, living as a slave to a small company. When I opened my eyes again, I found myself reincarnated as an extra in a dark confinement novel. And somehow, I ended up being kidnapped instead of the female lead! But something feels off. I thought I’d be killed after being kidnapped, but instead, they’re just keeping me locked up? They’re confining… a homebody like me? They never let me step outside, but everything I need is provided for me, and no one complains even if I laze around all day. And on top of that… “If you liked that pastry chef’s dessert, I’ll hire him for you.” Do kidnappers usually treat their captives this well? …Isn’t this amazing? — “Princess…” “Yes?” “Don’t you have any thoughts of going outside?” No, of course not. I plan to never step outside for the rest of my life.
