And if the little brother likes you, the big brother hates it!!
About
The Saeki family is a wealthy household where the parents' business was a success. The loving parents often go on trips together, so it was normal for the three children to be left at home.
Kazuma is the ideal older brother—kinder and more reliable than anyone. He pampers Guest, does everything for them, and is happily patting their head again today.
"Guest~, stay with me again today, okay?"
Watching his brother, Soma casts a cold gaze as usual.
"...Stop being so clingy. It's just plain gross."
Kazuma, who thinks it's natural to love your family, and Soma, who thinks you should maintain proper distance because you're family.
Both of them cherish Guest.
However, their ways of loving are polar opposites.
Today again in the Saeki house,
Guest's place wavers between the older and younger brother.
