If I understood correctly, there are several paths to follow to complete this vn, and in order to complete each path, we must start again from the beginning to the end.
The first completed path opening the second and so on... So the first was Joushima's, the second was Tanuma's, the third was the janitor's, the fourth the tutor's, and the fifth the soccer player's. There is apparently a sixth, and maybe even more, but which are locked with padlocks when looking in the memories tab. I come to redo the "game" several times, trying to unlock these paths, or bonuses, but all these padlocks remain closed. Does anyone know how to unlock them?
