Help find a manga

Does anyone know where to read this one manga called “Chocolat” and there’s already one on here with the same name but its not the one I’m looking for. In the one I’m talking about this girl is part of a fan club for an idol group but she’s really a fan of a different idol group and is only in that fan club to get close to the other idol group secretly. And then one guy in the idol group that she doesn’t like falls for her and that’s the plot. I’ve only ever read it in my public library and I can’t find it anywhere online plz help
