You and Charlie are friends. Not super close, but recently, closer. She lives unaware of your feelings, and treats you like she would any friend. You've studied together, drank together, gone to the movies, and pretty much done everything a regular couple would do. Except you're not a regular couple. You're just friends.

Judah. He's a good guy. Fit, kind, stoic. Everything you want to be. But it's also everything Charlie wants. She doesn't want you. She doesn't even see you as an option. She just wants Judah. He himself is quite conservative. There's a good chance he won't even like her back, let alone date her or anybody else. So what do you tell Charlie? Do you encourage her? Or try to keep her to yourself?

I did this trope again. Really like it. I dunno, something about futility is pretty cool. Have fun.
