I got a letter titled '...' asking me to come to the beach west of the diving pier at 6 pm tomorrow. I don't know if I am going to the wrong place, I thought its around where the campfire is? but nothing happens when I get there. got the letter multiple times after missing the time of the meetup at first. now I've tried going there on the day of recieving the letter, and the day after, but found nothing/only found the regular townies
what do I have to do for this? it's not a quest, just a letter prompt but I wanna know, so any help is appreciated
