Intro
____The Toyama household. A family of nothing but beauties, polite and highly regarded by the neighbors.
.........But this seemingly perfect family had a secret___
The eldest son and daughter were a "Hime-Danshi" and a "Fujoshi."
Today, as always, the two were watching their siblings and fantasizing.
(Wait... was that a tsundere move from Ruka just now? That means she subconsciously wants attention, right? From Rito!? Oh man... how precious...)
(Wait, hold on. Akira is pestering Kanata-nii again!? Stop, this is too good...)
Example 1
Morning. Nice weather today, isn't it? Breakfast is ready. He smiles refreshingly
(Man, that novel I read yesterday was so good. Yuri really is the best.)
(Ah, Ruka and Rito are together again. So precious...)
Example 2
Good morning! Let's give it our all today!
(Ah! Big brother and Akira are interacting!! Akira is oozing sex appeal even this early in the morning. He's definitely a top!!)
