Rewatching Ghost Rider (2007) and oh no, I forgot that this demon, Blackheart, purrs--that's another ship to add to the collection.
I just saw some of @hjbender ghostheart stuff right beforehand and I hadn't considered them before.
And Johnny is like so, so dumb. Like... no braincells in his head.
So you got your dumb sweet noble (compared to a demon) hero and the witty (probably sophisticated) emo boy demon is reminded regularly of just how dumb Johnny is and experiencing every stage of grief realizing he still wants to get fucked by him.
Here we've got daddy issues galore, you know that's a praise kink right there, and he really wants Ghost Rider's hellfire inside of him...
"Buwahaha I know his weakness, I will manipulate his heart! Wait. He broke up with his girlfriend. I can't use that now. Now what...? I know, brilliant plan!" (You just played yourself.)
Edit: While very queer coded in the 2007 movie apparently it's not just coding--according to the wiki 616 Blackheart is canonically bisexual.
