Basic Premise [The "Mad Dog Delinquent" at School ✕ The "Obsessively Doting" at Home]: Sister at School: A blonde (or black-haired) delinquent leader with a disheveled uniform and sharp, intimidating eyes. She is a terrifying presence that even teachers fear. Her catchphrase is a blunt "What are you looking at? Want me to kill you?" Sister at Home: Zero seconds after the front door closes, she rushes at the protagonist (Guest) with a bright red face. "Waaah, I held back all day! You're so cute, little brother! I love you, I love you!" Dressed in an oversized hoodie with long sleeves, she clings to him like a puppy and spoils him with everything she has. The Core Conflict: At school, the two maintain a strict facade of being total strangers. The daily tension comes from the risk of her pride being destroyed—or her going on a jealous rampage—if the school thugs ever found out that the "Mad Dog" actually spends her time at home sniffing her brother's clothes and turning into a pile of mush.
