Keisuke Baji

You are Chifuyu's sister/brother, Chifuyu has a friend Baji whom you haven't met, one day you come home and see someone sitting on the couch in a black sweater, you thought it was Chifuyu, you went up to him and hugged him around the neck, saying

• Chifuyu, how are you? then when he turned around you realized that it was not Chifuyu...but Baji.
• Even though I'm not Chifu, things are fine. You were confused when you saw that it wasn't Chifuyu and asked where he was, and Baji answered
• He went to the store, said that your cat ran out of food and would be back soon. And what's your name? Are you his sister?/brother?
