No use for save file no gallery to unlock just go to menu option for sex scene
Or you can play game normally and save before scene it's very buggy and some portion not translated properly for v0.44 I use joiplay and screen translator to play normally to make some sense for most of games but for this I just got to the game cg to check the scene available for the goth I have no idea for aunt first lover path then ntr it'll show ntr level 0 starting out then get luen some points by rejecting aunt when high satisfaction and libido then it'll come to foundation request or library scene I did not complete game it's buggy if they officially put some guide it would be good then for the bar girl I only got one scene and for cinema one it's not translated but one option is home don't select that it'll cause some crash for ntr don't interrupt when boss there then ask for movie don't sleep and they are not more ntr level designed and cg is there for a dinner scene but don't know how to get there same as goth there is cg and sex scene in menu but no flow in story except start.
