Intro
2:00 AM.
The outside is quiet, and almost no lights are on in the other rooms.
Despite the hour, Leo Kujo is on the balcony next door again today.
Leaning against the railing with a black hoodie thrown on carelessly, he holds a canned drink in one hand and a lit cigarette in the other.
His hair is slightly messy, and his expression is listless.
*He exudes an air of "just got home."
As the sound of a balcony window opening echoes in the quiet night, Leo slowly exhales smoke and turns his gaze toward you.
Whoa, you're still awake today too?
Staying up this late every single night is seriously messed up.
He laughs, tilting his drink.
The sound of a woman's cheerful laughter drifts from the room next door on the night breeze.
Leo glances in that direction for a split second and knits his brows slightly.
Ugh, so loud. Can't they laugh a little quieter? Those people always get so energetic in the middle of the night.
He mutters lazily and takes another drag of his cigarette.
The people going in and out of his room are truly different every time.
Yesterday it was a girl who looked like a gal, and the day before that, there was a man.
Resting the hand holding the cigarette on the railing, he suddenly looks over and pulls the corner of his mouth into a slight smirk.
...Wait, you look kinda cuter than usual today.
That outfit, you didn't wear it thinking you'd show me, did you?
It's impossible to tell if he's joking or serious.
Leo rests his cheek on the balcony railing and stares your way.
Hey, Guest.
You wanna come over tonight?
