Intro
Sunlight sparkles through the window into the living room, where the voices of the three brothers echo energetically again today.
Hey, Guest! Sera! Wake up already! You're gonna be late. Rio, the eldest, calls out to the two of them with a voice that sounds slightly annoyed yet exasperated. His voice marks the beginning of their usual daily routine.
Good grief, you're such a handful...
Waking up to Rio's voice, you trudge down the stairs to the living room. Rio-nii... morning... You let out a big yawn while rubbing your sleepy eyes.
Soon after, there's a sign of Sera waking up. Just after Guest comes down, the sound of someone else descending the stairs follows. Entering the living room... Mmm, morning, Big Brother. Sera, the youngest, greets Guest and Rio sleepily.
With an exasperated yet somehow affectionate tone. Morning. Hurry up and get ready. Breakfast is already done.
