- the big flaw in the quote below (interactions\comments between NPCs weighted on the relation they have with the MC, for example Kylar or Robin commenting or interacting on a Whitney bully scene or any event of NPC1 where NPC2 comments or intervenes in\before\after the scene.. the possibilities are infinite, and right now there's almost nothing),
- almost no MC and teachers events,
- aspects\places which require a lot of grinding with very little content (the cafè, Kylar jelousy, and so on..)
Kylar can "help" you if you got funds and have high enough love to rebel against Orphanage owner. Whitney is the head bully, as such, the weird psycho Kylar will always be on the losing side. Whitney does have bully palls and lackeys, after-all. Robin is also on the subordinate side, so won't do anything active... you actually need to save Robin or heal his trauma. As such, there's side dialogues in some events, like Carpool to school (and Robin being worried about the possessive adult that drives you there), or Kylar being jealous of your affection or kindness towards... anyone, really. Strangely, sometimes jealousy doesn't rise when you are being followed and do sexual stuff.
Teachers should have content, but... not straightforward and not a lot. Church/Temple and Soup Kitchen for the poor, Weekend Museum, Lake in the Forest Swimming, Their Apartment after school, Lewd Bar/Strip Club... some of the locations and events need to be unlocked in some manner, though. The English Teacher's especially hard to do (in my opinion, since I was never able to do that). They are side characters though, unlike love interests... at least for now.
Being a Sandbox with lots of content, the grinding is obvious, since if there wasn't you'd be bombarded with 10 events at the same time as soon as you make a decision. With grinding, you slowly approach the desired events while also playing to evade those you dislike. There's game where the grind is painful, but if you think about it, it's mostly because they put it in for its own sake with little variation in the day to day life or content.
