I need advice regarding using my free time.

I beat Rize dungeon & teddies boss fight in one day how should I use my free time? Yukiko is always coming out the woodwork asking to hang out… I ain’t complaining. I haven’t hung out with yosuke in a fat min. I don’t look Kou’s way. Yuki is dealing with her mom :/. I got a couple books I’m working though. I got to restaurant that boost your stats but I just want to make sure I’m using my time right. Anything would help. Thank you everyone.
