Alright, first things first, you can theorize, sure, but as of right now there is no confirmation on who Sage's parents are nor do we even have an insight into their personalities or character, so why would you even bring her parents up in this discussion, saying that her parents 'want something fancier than the MC'.
Secondly, planning problems in their relationship? I don't even remotely think something like that would occur. With this statement, you're implying that the whole quarrel between Chad and Sage where Sage got mad at Chad for not even caring about her and just asking her to help him, while MC was eavesdropping, was staged? Additionally, how'd Sage know beforehand that you'd be her fuck buddy? Unless she's psychic, this is highly unlikely.
I don't remember any conversation where Sage implies that you're her errand boy either. She's never asked the MC to do anything other than finding out if Chad was cheating, which although seems weird since they were strangers before, isn't that big of a problem. The other conversations they've had, MC was the one who offered to teach her guitar, it was his choice to care for her while she was sick, and she even felt sorry when she missed out on MC's birthday.
If anything I typed is inconsistent with the game, I apologize, because I can't remember everything either, but people really gotta stop assuming everything without solid, canon proof.
Same man, I got that "off topic" edit too, and all I said was that I'd be replaying to try for a harem route lmao
I'm guessing that Riona's stalker will be somehow linked to Quinn's money thief, and might be related to Vinny as well. I'm hoping that it doesn't end up too harsh though, I don't wanna see a r*pe scene in the game. Hoping that whatever happens the girls are gonna be safe.
