Its not... terrible. But it is... horrible.
Like, I'm down with it conceptually. But the execution of it is just so laughable and dragged out and it ends up being more of a stain and a reason to dislike Erynn than a plus to her story.
Instead of activating protector mode to stop Ethan from fucking with Erynn, I end up activating "shut the fuck up" mode to stop Ethan from shitting up the story with his stupid face. I want MC to stop Ethan to get him out of the story, more than I want MC to stop Ethan to save Erynn from him.
