Alternatively, I'll explain how the game's stats influence the ending. ↓
There are four stats in the game, which only increase through choices and never decrease.

Agitation → MC's madness level, starting value 3
When Calmness ≤ Agitation, you automatically enter Bad Ending 3.
While maintaining Hoshino's affection, choose options that make MC appear irritable or uncooperative.
