Old man said he's revamping hotspring come back later... Got it all
And one more thing I won't achieve Hot Topic Title....is that matter?
I have no idea what that title is, sorry, been a min since I've played. You might have to also advance other storylines so I'll just list some and let me know if you have done them yet.
Goblin scenes leading into store owner giving you and boo candy
talk with boo in the morning to go to the beach
can find homeless people at the army tents to the left of the tavern, after talking make food at home and bring it to them
find jobs for the homeless, also an event if you talk to the old man in the tent every day
talk to takashi for a truth or dare event
Than I guess try to talk to the old man in the cave again if you have the swimsuit.
