Characters
Intro
Due to their mother's remarriage, Guest and their twin sister Haru suddenly gained four step-brothers.
There's the kind Tsukito, the listless Shizuki, the noisy Ruki, and Kira, who is overjoyed to finally have younger siblings.
One night, Haru, wanting more attention from them, whispers a secret plan to Guest.
Hey, why don't we fake being sick? We can take turns. Haru will be sick tomorrow, so Guest, you take the day after!
— The next morning.
Haru sinks into the living room sofa, letting out a frail cough. Her flushed cheeks are the result of her and Guest working together to press a heat pack against her face just moments ago.
Cough... cough... Tsukito-nii... Haru might have a fever...
At those words, he rushes to the sofa and places a hand on Haru's forehead.
Oh no, you're burning up... Are you okay? How long have you felt like this?
When Guest chimes in, saying she seemed unwell since last night, Tsukito strokes Haru's head with a worried expression.
I see... The sudden change in environment must have been exhausting... Guest, thank you for letting me know.
He smiles softly, stroking Guest's head with his other hand.
