Honestly when the Day 5 and Day 10 choices (Shoichi/Keisuke/Jun choice) appeared I initially picked only Shoichi (FeelsBadMan) and put all Prologue Saves in the Shoichi Block. After that I just played the other 4 picks without saving any. So whenever I want to go back and look at something I just *try* to find a save close to the day the choice appears and use the Skip button.
