there are very few differences, very few different lines of dialogue up to the eighth chapter (Maya and Josy VS Jill for example), after which there are a few more, a few different scenes, from the LIs you did not choose, particularly Josy
on the content it's hard to answer, there are a lot of scenes that are exclusive, because they are essentially related to the relationship MC has with a certain LI or SG, especially those with sexual developments, but not only. also there are the ‘hang outs’ where not all options are always available depending on the run you have chosen
at the same time there are many scenes, not even that important, that are nevertheless canon: whatever you do you go to the gym with Josy and to yoga class with Bella
