Is he just being nice?

So this guy at my job.. we work in different departments but lately I’ve been noticing little things he does when I’m around. I think he’s cute and everything but I’m a little cautious since it’s work and I’m not sure if he’s just like this in general or being nice? Every time I see him, he’ll always be like hey Jenny how was your night last night? Or if I tell him I’m going for a run after work he’ll ask me how my run was. He’ll give me an eyebrow raise when I see him. He’ll smile at me and wave hi. Once he asked me which location I was gonna be working at because I’ve been bouncing between locations lately and I haven’t been permanently put anywhere yet. I just wanted to know anyone’s opinion on this. Thanks.
