If I had a complaint it'd probably be that the protagonist comes across a bit too much like an incel on the verge of becoming a serial killer. His actual dialogue, what he does, how he reacts and such is fine, but Jeez his thoughts those first two days are ... that's one man ready to go off the rails. Toning him down a touch wouldn't hurt, I feel, and frankly would feel more consistent with how he is in the actual interactions.
