Everywhere at the end of king: Boyfriend dies of dementia and King tells him that Girlfriend keeps bringing him back, that it's an endless cycle of lucidity, dementia, and death for him, and that if she ever lets him go she'll pass away out of a broken heart due to her attachment to him.
Like:
"You're back here again?"
"?" My mind... It's finally clear...
"You always don't remember at first..."
"!" Everything! It's coming back to me!
"...but then it all comes back. Such a pity, really, being stuck in an endless cycle of coming here until your girlfriend brings you back to the overworld to have your brain rot all over again, all because she can't give you up, because you two just had to love each other soooo much, that without any hope of having the other again, you'll just fucking die."
"..."
"Let's sing."
