Can a guy be into a girl immediately if he finds her only average looking?

This guy is obsessed with me after our first date and keeps complimenting my features but I’m not really pretty. Can guys be super into a girl after one date if they find her just average looking? He also hardly ever tells me I’m pretty, he just keeps telling me that I am soooo cute

Can a guy be into a girl immediately if he finds her only average looking?
