Guys, Is "Netflex and Chill" mean he's interested?

So I kinda like this guy and I offered to come hang with him after he told me he was gonna chill with netflex, but my plans changed so I asked for a raincheck and he said "sounds good" then when I chatted with him later he said " I'm serious about that raincheck" and another time when he noticed I was down and asked me "why so quiet?" Then said again be was serious about the raincheck.

so do you think he may liked me or just wants to chill?
