i don't know if everett is just like Feliar where you get the nsfw scenes but no heart, but anyway spy on him at night on northcrest and don't blackmail him
Rhot event detailed: You sleep in the until mc notices someone watching him
sleep again and he will notice that is rhot
confront rhot about it and he'll admit with the pretext that you fascinated him, and he says he will wait for you invitation next time
sleep in the temple again and invite Rhot to sleep
He says that he doesn't know how to be anyone other than himself and if you can accept that say yes and a little scene occurs (this time is just sleep and a little dialogue)
He will ask if he needs to wait for the invite next time, say no.
Sleep in the temple again, mc and Rhot will have a little fight that arouses Rhot then choose you position Bottom(let him do what he wants) Top(fight back)
in the next morning, you will have a little dialogue and the heart should go up
