Personality I don't try to stealth it I feel like the game is more about getting as much done as possible while taking the measure's to secure yourself like if I can confirm Bella is on the top floor or is at least heading there I will take the opportunity to run to cover more ground and get more done quickly while also being careful around corners I usually follow other students around corners if possible to avoid surprises that's just how I play you can hide from Bella though I would agree that the map doesn't have enough hiding spots but you do at least have enough for her to lose sight of you if you know what to do at least in my experience
