LF fics where something happens to either of them and the fact that nobody knows they're involved means the other one isn't told anything/is trying and failing to get informed?
Okay, the way I worded it is kind of convoluted but hopefully it's still understandable? I'm looking for situationship era mostly, but the important part is that *nobody* knows they would care about what happens to the other. There can be a relationship reveal as part of the fic, I just mean that at least initially there's a focus on how they aren't connected publicly and how that's affecting them negatively in this situation.
