Once upon a time, there was a little girl named Lucy. She had a sister named Lily. They loved to play together. One day, they found a big, interesting box in their room. They didn't know where it came from.
Lucy said, "Let's open it!" Lily was scared and started to tremble. She said, "What if there's something bad inside?" Lucy hugged her sister and said, "Don't worry, I'll protect you."
They opened the box and found many fun toys inside. They played with the toys all day and had a great time. From that day on, the sisters were never scared of interesting things they found. They knew they could face anything together.
