I am softlocked the same way. I thought the game was forcing me to get the clubs introduced so I tried doing that first thing but now it seems I can only either join the student council (which I do not want to do) or absolutely nothing else. Nothing home, nothing in any of the rooms in schools... just people who won't interact, no option to pass time or even shower...
Edit:
I solved it. You need the tutoring skill (maybe swimming works too?) as that option is still available. Not having the adequate skills will soft lock you.
