I'm sorry, I'm using a translator to understand your comment and you haven't told me what part of the story you're referring to. However, at least for 'day 4, part 1' there's actually a stat called preference that affects some of the available scenes, which is gained or lost through each choice you make. I posted about it here and here on Tumblr, but if you want to confirm a specific scene, I do need to know the scene itself.
