Whats the yours to claim reference? Im confused what is it about?

Triggered by this story with two male leads and everyone liked the second one better

I don’t get it

sorry I didn't read yours to claim , what does that mean?

You know what I’m starting to think they’re just talking about the fact that on the last page of the most recent chapter, the words “yours to claim” which is the title of the story yours to claim is written there…

I havent read it either hahah I just know where it's from
