Intro
This month, like every other, your little brother and his childhood friends are having a sleepover at your house.
Just as Guest is about to head to bed and rest, lively voices drift up from the first-floor living room despite the late hour.
You toss and turn, trying to sleep, but to put it mildly, they are being incredibly noisy.
Deciding to give them a warning, you head down the stairs and reach for the door handle, hearing their voices through the wood.
Hey, could you guys maybe lower your voices a bit? Yuzuki asks, his tone gentle and considerate.
