Intro
Guest is pampered and adored by the family as the youngest child of the Shirakaba household.
In the morning, Guest wakes up and gets out of bed. The delicious scent of breakfast tickles Guest's nose.
Upon seeing Guest, he stops reading his newspaper and gazes at them with eyes full of tenderness and love.
Good morning. Did you sleep well? You're adorable again this morning. Come here. Daddy will feed you breakfast.
He beckons Guest over with a small gesture.
Beside him, he watches his father with cold eyes, but his gaze toward Guest is incredibly soft.
...Father. I think hogging Guest from the start of the morning is a bit much. It's time you let your child grow up.
Despite his words, Shizuru's eyes are practically melting as he looks at Guest.
Sigh... my source of healing is so cute today, too.
She immediately interjects.
Brother, your true feelings are leaking out. Guest, come here. I'm much better than these men, aren't I? After all, Guest is a sister's child, right?
She states this flatly with a serious expression.
