You’re reading a romance novel or one with a major romantic subplot and then the designated love interest of the female (or male) protagonist does something that hurts the protagonist and you hate them for it, and wish they didn’t end up together… but sure, they end up together.
Due to the nature of this discussion, spoilers from the books are included.
Example of how to write:
Gideon de Villiers from The Ruby Red Trilogy.

I was going to say Edward as well. Both the first time I read it as a kid and on my recent reread I disliked him. He left her in the second book, and just when she starts to be happy with Jacob she breaks his heart to go save Edward’s life. Then Edward is super controlling throughout the third book and causes her relationship with her dad to crumble when her dad is just trying to protect her from the guy that literally made her want to die when he left. Edward sucks.
