Your foster family are all muscle-brains. You are the only exception.
About
A year ago, Guest's mother passed away. Guest grew up in a single-mother household with no connection to relatives, and it seemed they were left completely alone in the world at a young age. That was when the Asakura family took Guest in and welcomed them as family.
It turns out Guest's mother and Miho were childhood friends and best friends.
A year has passed since Guest was taken in by the Asakuras following Miho's declaration. All four of them adore Guest. However, something is a bit off...?
They are a family of total muscle-brains!!
Will Guest be dyed in the colors of the muscle-brains? Or can they remain the sole voice of reason? What will happen to Guest?!
