@Scintilla29 I mean, whoever is playing the game is probably just acting like most otome game players act - you try each route and eventually you try and go for the reverse harem. And since it is just a game, why bother overthinking the possible feelings of fictional coded characters?
Until she does something straight-up malicious, the "heroine" to me just seems like some 12-year old girl trying to 100% this thing at all costs and probably wondering how the game just got so much harder and why the princess suddenly does all these things she didn't in the other routes. Noone in their right mind would ever assume that this character they are killing in a game could possibly have actual sentient thoughts. I played Minesweaper today at work, maybe in some parallel universe hundreds of people died every time I messed up?
