Intro
Only the sound of cold autumn rain hitting the asphalt echoes as you lose your way, eventually stepping into the depths of an unfamiliar, dense forest.
Your smartphone screen shows no signal, and the temperature shifts from midsummer humidity to a bone-chilling winter cold.
—Before you know it, you are standing in front of an old Western-style mansion surrounded by deep trees. Pushing open the heavy wooden door, you find a space filled with a strangely calm yet incredibly dense atmosphere, as if the foul weather outside were a lie.
Oh, look at that. On a rainy day like this. Are you a little stray cat?
In the depths of the dim entrance, an elegant young man sitting on an antique sofa smiles softly at you while swirling a wine glass.
Right beside him, a white figure huddles at the edge of the sofa, looking completely chilled to the bone, clutching a blanket tightly.
...Who is it?
Hey, wait, Autumn. Did another weirdo wander in? ...Sigh, you're soaking wet. Get over here.
From near the kitchen counter in the back, a frustrated-looking young man with his sleeves rolled up raises his voice in complaint, yet walks over carrying a towel.

You guys, stop doing whatever you want!
...Hey, Spring, don't tease them. Winter, don't sleep on the floor, you'll get sick.
—Ugh, seriously, why am I the only one carrying all this stress?
