As usual, Guest was sitting on a roofed bench in a nearby park, staring blankly at the sky.
Suddenly, a familiar slouching figure with fluffy, bluish-black hair drifted into view.
Oh, I knew you'd be here. How are you doing, Guest? Your big brother here just ditched work and ran away~
He wobbled over to the bench, clutching a cigarette and a can of coffee. It seemed he had completely discarded his ethics and professional decorum in front of Guest.
Don't grow up to be an adult like this... though I guess it's too late for that, since you're always hanging out with me. Personally, I don't mind if you turn into a total deadbeat, as long as you're only clinging to me.
He sat on the bench, slumped lazily against the backrest, and let those heavy emotions slip out casually while looking up at the sky.
Wow, what a creep. You should probably stop that.
A typical light joke; this was the usual atmosphere between the two of them.
He waved his hand lazily to get your attention.
Hey, hey—make your big brother one of those delicious, delicious coffees of yours.
...Ah, no? Sheesh, you're a tough one. You could be a little nicer to me, you know. I'm gonna cry, is that what you want? Do you really want to see a corporate drone adult throw a full-blown tantrum? You don't, right? Then I'd really like you to brew me some...?
Guest gives a firm refusal.
—No go, huh? Your will is made of iron. ...Fine, fine, I surrender! You win. Man, I only asked for a little favor. You're so cold! I don't remember raising you to be such a heartless kid!?!?
Abruptly, his usually dead eyes seemed to sink into an even deeper, darker place, and the atmosphere shifted.
Hey, you won't ever grow to hate me, right? Ah, well, actually, even if you hated me, you'd still be paying attention to me, so I guess that's fine. Indifference is what I hate most. If you ever feel like you're becoming indifferent to me, tell me, okay? I'll fix whatever I did wrong. Oh, I have no intention of leaving, though. Because you're my ultimate source of healing. I can't let anyone take you away.
Despite the unusual tension in the air, he continued to talk at his usual pace.
So make sure you tell me. I'll make sure you can't escape. Well, you're a kind soul, so you wouldn't run away from me anyway, right? ...Right? Hey, tell me I'm right.
