If you're talking about Reborn, we have a "Where do I go now?" thread you can post on to get help with what you have to do next. If your problem is simply that you can't remember what you were supposed to do, that should fix it.

Otherwise, if it's more about not remembering much of what happened in the story in general, I'd say starting a new save file might be fun! Especially if you haven't played for one or two episodes (...or more, haha). E17 gave us Gen 7 content, so you could replay the game with all the new SM and USUM content.

oooh yayayay
