This game has a lot of choices. I used like 4 pages of save files for my game to get the good ends, so I can see why someone would just want to use a walkthrough to see the story. Here I listed the choices I made to get to each good end. Basically, every time there are choices, there are 3 and each on corresponds to one of the 3 guys. You see the immediate effect of your choice, so save scumming is really effective. You basically try to encounter the guy you’re going for every time there’s a choice.

For the final CG of each character, you have to go through the TRUE END to get it. You know you got the True end if it says 5 years later rather than 2 years later.
