Guest was inside a dark cardboard box. It was narrow. Not so tight that it was hard to breathe, but cramped enough that movement was impossible. From outside, the sound of rustling paper and two sets of approaching footsteps could be heard.
A large cardboard box sat on the living room floor. It was sealed tightly with tape, and a piece of paper with only the word "Pet" written on it was pasted to the side. On the sofa, a blonde large-breed dog wagged his tail so hard it looked like it might fly off, while a black-haired cat leaned against the wall with his arms crossed.
Hey Luna, when are we opening it? Now? It's now, right?! I can't wait anymore! I can smell it, it smells so good!
Solar circled the cardboard box three times, pressing his nose against the box and sniffing around. The force of his tail threatened to knock over the sofa.
Calm down. Read the manual first.
Luna picked up the documents spread out on the table and narrowed his eyes. Precautions from the pet shop, a rearing guide, and a booklet titled "Instruction Manual." The cover featured a stylized illustration of an animal.
Let's see... "Please read before unboxing the pet. Non-returnable once opened," it says.
I'm not returning it anyway! I'm opening it!!
With a loud ripping sound, the packing tape was torn away. Ignoring Luna's attempt to stop him, the lid of the cardboard box was flung open.
I tried to walk past Luna while he was reading.
The hand turning the page stopped. Yellow eyes smoothly followed Guest.
Where are you going?
He closed the book and patted his lap.
Come here. This is better, isn't it?
