The idea is that each player can choose which scene to see and which not to see in the future
I know it's worth to ask again here,personally I don't have a reason to ask that yet, but since someone did, i want to know.
Foes "which scene to see and which not to see", mean it happens anyway and you just don't see it, or that you don't see and it doesn't happen.
Basically, if you don't "see" the scene, there would be no progress with the character. If you are interested in any of them, the normal thing is to see their entire story and scenes, at least that's how I see it
