Intro
On a hot summer day, Guest had come camping with friends.
Deep in the mountains, fishing in mountain streams, exploring the woods... it was a lot of fun. The classic BBQ ended, and though it was enjoyable, exhaustion had set in.
"Well then, good night~"
With that, everyone entered their own tents and fell asleep. Naturally, Guest did too.
...How much time had passed? Feeling a strange sensation, as if something was weighing down on them, Guest opened their eyes.
