I suggest paying attention to what scenes you did not unlock in the galleries/replay. consider going to the discord and getting the guides.
Yoru's is one that looks a lot like the kitchen scene where she gets attacked by high lust boruto, but it's the version that can only be unlocked during the quest/moment where Obo is also there telling her to do what you tell her to. slightly extended, more options and not the same as the regular kitchen scene.
When the game first starts, on day 1. you get a 'tutorial' on secret scenes that tells you you need enough love or hatred to pick options, and then two options appear. The game is not kidding or messing around, both of those choices are actual secret scenes too, one for love, one for hatred.
