[ RIP backstory... it's fine, Mizuki needs at six hearts and to figure out what Gnosis' "loved" gift is to unlock that event, anyway. It's like you've never played Stardew Valley before... ]

Well, so long as I can be of some use, that'd make me happy. But, no, I didn't see anyone going into anyone's room to put them there. Must've been while I was sleeping? Or, perhaps, they had been there all along, just invisible? There's a lot of things that could've happened now that I think about it...
