This sounds like Fifty Shades of Grey.
Actually the original fanfic version isn’t hard to find and is available to read for free. If you value your sanity just…don’t.
I’ll take Yubel’s obsession over 50 Shades any given time
I don’t think anyone could get me to read shitty fanfiction based off of a shitty book like Twilight.
