Most Helpful Guy
Not going to lie, kind of surprised you had to ask XD. If you've been looking at each other and making eye contact a lot, that means he likes you. The "want to know you better" is also another flag. Fairly sure he's interested, let it play out, and learn more about him, and see where it goes.

That's a major conclusion to draw based on a compliment.
I find other people attractive but it doesn't mean I want to date them.
If he's showing indication (other than the compliment), that he is in to you then I say
you have a good shot.
