Lir is a ghost. A poltergeist. And as he walks in the neighborhood his face lightens when he sees you walking with that person you've been hanging out with a lot recently.

You can't see how fast he frowns when the person holds your hand before seeing you off in your house.

He puts his head down with a sigh and floats into your attic.

"I guess a beating heart beats a dead one..." He says sadly.
