Mei's face showed an embarrassed expression. "Uh, I wasn't doing anything!"
Otis's eyes shifted toward the cardboard box, taking a glance. It seemed like… something he had given her. Wait, oh, so that's what it was. Otis immediately understood.
Mei pushed Otis toward the dining table. "Right, I already bought the paper, so when the time comes you write the questions on the sheets."
It was only then that Otis noticed several stacks of white paper, red paper the size of a palm, and a stapler on the dining table. Mei pulled out two white sheets and said, "You stack these two together, the first sheet is for writing the question, the second sheet is for writing the answer, got it?"
Otis understood what she meant, then looked at the stack of red paper on the table. He couldn't help asking, "What's the red paper for?"
