Let me know if you if you don't like my ideas & I will stop sharing, just say the words!
I was thinking about some vanilla personas evolving into feedes & some gaining unique traits like I mentioned with the Secret Feeder Persona be actually sneaky with trying to entrap the player.
Brat & Rebel having a demanding trait where unlike other feedes who wait to be feed they would demand to be feed whenever they are hungry. If you deny them to often they with get upset & won't hang out with the player for the next few days.
The Brat would boomerang 🪃 their love back onto you to make it harder for the player to say no, while the Rebel would have to be placated with hanging out with them to ease their annoyance at being told no.
These suggestions are made in mind that after some big event to make a vanilla girl into feede & their Personas with gain more texture to them to go with their already existing favor to stand out more as apart of their bonus.
As you know I have more ideas 💡 but I will save them for a later date 📅.
