There are manga that do not include the name of the chapter in the actual pages, and there are some times when the reveal of the chapter title is delayed for dramatic effect (e.g. Kaguya-sama and "I Can't Hear the Fireworks")
However, I haven't seen any examples of the latter that weren't purposefully written to not make sense until the reveal. Do you have any examples of either where the chapter title actually spoils a dramatic event in any meaningful way?
