Excellent update, all the scenes were great especially the first one, I find interesting the incorporation of the librarians, but there are some things I suggest to add without wanting to impose anything at all:
1) I think it would be good to change the nicknames and relationships post first choice, either by adding a section in the phone or somewhere (I happened to choose the wrong term for the wife of the father and also for the mother's sister xD and replay everything to change some name or nickname is problematic).
2) More than something to add is that I don't know if I didn't detect well that you should go up in some girl to unlock her scenes in an intuitive way or is that it's difficult, I don't think it's wrong that you have to talk to her in some way to unlock some scene, the thing is that I don't see that you give many clues to know which is the correct one for the girl in particular.
3) And lastly and a personal request I miss the anal, I know that the pregnancy weighs a lot (I fully support it) but I never understood why you have to make it exclusive, again this point is just a personal preference that I prefer to be ignored completely if it goes against your vision of the update in any way.
