So I'm writing a fan fic about a guy in high school who crushed on this girl for two years and he gets bricked when he sees the girl's phone wallpaper was another guy whom he assumes as her boyfriend. Turns out that the guy in the wallpaper is an idol and the girl was an obsessed (sort of, not really because she just doesn't want to date anyone because she likes the idol) and the story just goes on on how the guy will get the girl.

Please don't answer if you're just going to get in my nerves, I need people who are actually willing to give suggestions. Thanks in advance.
