Thanks for your reply, so I continued playing
But I believe I encountered a bug...
Did I return to the original scene in this place? Then I met the two characters again, and they had joined the team.
(I am a person who gets lost easily...so I spent more time than expected in this underground scene LOL)
p.s
I finally found it!!!
It turns out that restoring PV means restoring HP. Because the life value displayed on the battle screen is HP, I never realized it...
