you have ten days left, but a few of them are exam days
I think up to the 22nd you can. I know the game gives you a couple of days after the palace deadline to do a few. I think you can finish them within that time frame if you really hustle.
Thanks folks.
Looks like it'll be a tight squeeze for me to finish off the Empress confidant with those exams looming. I'm actually surprised I came so close to getting all the confidants without using a guide. This game seems a lot more forgiving than P3 FES and P4.
