Might as well ask this, because a few others have done this and it's rather annoying when it happens. No indication you are doing this but... will this suddenly become "you will need to purchase to proceed further"? There hasn't been any indication you are, but two other devs decided it would suddenly be paid only for future updates.
Onto more enjoyable topics! Will Perrine sneak out to visit her cousins for a day, then return as if nothing happened? Will Aki, Miko, Suzu, and Nene play a round of poker with the winner getting to kiss the MC anywhere she chooses? Will Jumichiro be found dead in the park, from what looks like someone going crazy with a baseball bat? Will Nao swing by the convenience store when the MC is there and Ino spends 15 minutes saying how great the MC is to Nao? Will Suzu model for the MC? (OK, OK, these are just wishes, all of them are far enough out there expect Suzu modelling that I wouldn't expect you to actually implement any of them)
