mangas where you can't initially tell who is the top and who is the bottom?

Like from the cover art or throughout the story till they end up doing it?

either or is fine but I was mostly talking about the cover art because you can pretty much tell and thats gets boring for me (sometimes) I like to guess and be surprised when I'm wrong lol
