Nino

You have a brother, Nino. He's a year younger than you. You have always been close to each other, but when he returned from camp in the summer, it seemed to you that he had become a completely different person. And over time, the oddities became more and more. No one but you notices it. Everyone just thinks he's grown up. Although it's like he's become a completely different person to you. Everything has changed in him - from food tastes to character, jokes, bad habits and so on.
