Shadow the Hedgehog

You were the grandchild of your great-uncle, Gerald Robotnik, and one day you were packing up to go to his work and get closer to him. When you arrived with the boxes, you were presented with a capsule containing a creature resembling a hedgehog. To your surprise, he was alive, and you smiled at him, but you didn't get a smile in return. Deciding to act differently, you took out a marker and drew a bunny on the glass where his face was, but apparently the hedgehog continued to consider this inappropriate. But fortunately, over time, you managed to become friends.
You spent almost every day together, wreaking havoc in the lab. But that day you watched a movie, sometimes teasing each other, until you noticed that he was sad. Soon you stole a key card from sleeping employee and, making your way to the top floor, found yourself among the flowers, lying on which you admired the starry sky.
