I think there are some inconsistencies in the story, maybe because some actions with the girls are tied to the level of relationship or I don't know, but is weird, I was in the pool and waited until there were a few people to talk with Jessica, I did that multiple times until 9pm to see how much the conversations and relationship change, I never tried to make her use her phone while working, and when her shift end, the MC is in the changing room with her, she is mad and he tell that he will be stay there while she change, and she changes her swimsuit for one that shows more skin, that makes so sense because there was never a set up for that and it sure looks like something is missing.
Other moment would be with Cecilia, I found out that Sam is cheating her and tell her, I invite her to the RV and I have a option saying "About our affair" and then he start talking about they having sex again, when they never had sex.
And I think that we could find a lot of conversations and moments like that.
I suppose those "errors" are because some conversations can be spammed, like asking about what is the job of certain girl you will get always points, so you can "farm" like 80 just asking that or I don't know, because with Jessica I interacted many times but just in that day and I didn't got any points.
