supernatural storylines

I want to write a supernatural story but i hear that the ending are pretty predictable. But ig that’s with werewolves and vamps huh? I don’t want to grove to many details of my upcoming story because it unreleased but the MC character is like super powerful and rebellious while the Li is a sweet, caring werewolf.

What is the most predictable endings that y’all noticed? Maybe I can try to steer clear of those.
