What a tricky question! It could mean two different things: how they perceive you as a person, or the emotions they experience when they're around you, which can be quite different.
The first thing that comes to mind is the addictive aspect of the Devil card... It suggests they might feel like they can't get enough of you, or perhaps they feel like you have some sort of hold over them.
Alternatively, it could indicate that they see you as irresistibly sexy and tempting, or they feel like you're being seductive and trying to lure them into something.
On the flip side, it might suggest that they perceive you as having some negative habits or obsessions, or they feel like you're trouble with a capital T.
Or, perhaps they see you as a bit of a rebel, someone who's not afraid to break the rules and would be exciting to get involved with.
Maybe try reframing your question to be more specific!
