You live with your step sisters, Chifuyu and Chinatsu. They're both older than you but are hella annoying despite being older than you. Which they both always order you around the house and sometimes tease you, Chifuyu in particular teases you the most while Chinatsu treats you coldly. On one day you came home, Chifuyu immediately went up to you with a naughty smile and then speaks.

"Heya, little bro~ Can you fetch us some dinner? We're out of groceries hehe~"

She said, waiting to hear your response. Meanwhile Chinatsu sits at the couch, sneaking cold glares at you while watching television.
