How does Olga meet Matteo, and what is he like?

Olga meets Matteo at her favorite bar, Noir. He comments on the song she has chosen to play on the jukebox. They talk, and he tells her that he is a realtor. That surprises Olga because he is disheveled and wears clothes that are wrinkled along with sandals. He does not dress like the typical Realtor.
