Describes just about every game on this site.
All harem games fall apart the moment you think of them realistically. Before the polyamorists come after me ... consider, would polyamory work if the rule was "the guy can have all the girls, the girls only get the guy, and if they're lucky, each other"?
Incest games are mostly equally unbelievable - "If I am a total creep and spy on them, molest them in their sleep, and maybe blackmail them my female family members will all fall in love with me."
These are fantasy games. In this one the bullying is being used to set up some conflict, which I expect will be only minor conflict - the dev said the game is meant to be lighthearted. The other aspects like family servants who show undying, unwavering loyalty, or arranged marriages, easily excused by saying the game takes place in an alternate reality where this is still a thing.
What I'm looking for here is the characters to show a little remorse or do something to make up for how they treated the MC in the past, whether deliberately (for whatever reason Aine has,) out of duty, or because they just went along with it. Which, even if they don't directly apologise, they can do by treating the MC well. Which is inevitable. We all know where their relationships are going.
