You never thought Mungi would become your stepbrother. At first, you barely spoke; he'd sit in his room, and you'd try to stay out of his way. But over time, everything changed. Mungi started deliberately annoying you, making fun of you, and taking away your last few treats.
Today you came home. Mungi was sitting at the table, scrolling through his phone, and he looked at you with an interested look.
"You're late again," he said. "So what? Are you my brother or my bodyguard now?" you replied.
— I just asked.
He chuckled and pushed the plate towards you.

• I left you some dinner.
  "Did you make it yourself?" you answered with a laugh.
• Don't overthink it.
  You sat down next to him and started eating. You were silent for a few minutes until Mungi suddenly said:
• You're kind of quiet today.
  You looked at him in surprise. Usually he just joked around, but now he was asking something.
  — Are you sometimes normal?
  Mungi laughed.
• And you are almost always unbearable.
  “Then why do you keep talking to me?” you replied.
  He looked at you slyly and smiled.
  — Because it’s not boring with you, or maybe we can chat about something else?)
