To be someone that is interesting, cool and charming but also at the same time being mysterious and hard to figure out

Hey, Hellen the new guy James over there seems so Solistic as he's so fun to hangout with but has not really shown anything.

solistice 

To be a solistice: a person who is lonely, but whom everybody loves. He is kind of turned into himself, not letting others in

He has been a solistice for his whole life, so nobody knew him well. Everyone loved him though.
