I have a question. I'm on loop 10, but when I want to talk to Jousuke at night, he doesn't appear. Do I have to keep doing the loops at the party until he appears, or do I have to do something else?
Depends how far did you progress his quest, here's full breakdown:
- attend Friday party
- meet Yosuke at night day after party
- get the thing for him from science student (random event during the day)
- attend 2nd party
- meet up with yosuke again to give him the thing, he will ask for pizza
- cook pizza in the kitchen
- meet up with yosuke, he will point you to kan's room
- attend party to break into Kan's room to get lab key
- run until you reach lab
