What does it mean when a guy says there's something about you. I can't work out?

So got talking to a guy. He seems really nice and we get on good so far. We have spoke all evening. He said there's something about me but he can't work out.

We been talking of our exes and about what we want in a partner.

Does it mean intriguing? Good/bad
