Someone that you have had feelings for in the past and have gone, but, you still think highly of them & still acknowledge that they are attractive, anagous to a ghost. Someone that was alive, is no longer, and you haven’t forgotten about them.

Also may be willing to date if asked, because you know that it wouldn’t be hard to regain feelings for said person.
