Why would a guy want to spend 10 hours with me for a first date?

We both find each other attractive & get on well. Had a few long phone calls & texted. However it’s only been a week. When discussing first date he set it very early and said he has a few ideas.

we did a few things but then he asked if I wanted to come to his to watch a film I declined. Didn’t hear from him until 4 hours after I left and he said shame you didn’t stay.

im just wondering how does this guy even know we’re going to get along? Isn’t pre planning that many hours in advance a bit odd?
