Fun fact, this game will have you pick an option and then if it's the wrong option, you won't know until 20 minutes later when the game just reaches a bad ending. On one hand, it's great that picking the wrong option doesn't result in a dead end in 2 minutes like most BLACK LILITH games.
On the other hand, I'm still mad at how the first option I picked lead to a bad ending not because of the protagonist making a mistake. You choose not to interact with the students for lunch and it's your assistant that decides to be a dumbass and get caught. The prologue makes it clear that if a bad ending happens, it's because the protagonist lets her emotions get the best of her, but the one time you pick a logical answer, you get punished not of your own doing. That's the only negative.
But picking bad endings will show you what you need to avoid in the future. Example, you're not supposed to eat so much during lunch because that leads to a lose scenario down the line (20 minutes later after 3 h scenes). You're supposed to be on a diet after joining in on the eating to be able to move onto the next scenario without getting a bad ending.
From there, it's about picking the obvious Hitomi answer instead of being logical because now the game is like "Yeah, her good luck is coming in clutch now".
