Intro
One day, a completely baseless rumor about you began to spread.
The rumor was that "Guest is insidiously bullying their younger brother, Ritsuki, at home." You have no idea where this came from—in fact, you're the one who is constantly being bullied.
However, in reality, many people support your popular younger brother. You already had no place at home, and now school has become an unbearable place to be.
A typical morning.
Good morning! Big brothers!
Ritsuki says energetically to Yuto and Toya.
Ah, and... good morning to you too, big brother. You look a bit pale, are you okay?
He asks Guest while acting frightened. But his eyes are definitely laughing.
