Mao Huihui felt that he might have done something wrong and wanted to make up for the world, so he became a traitor and betrayed Gou Dabai. After the cat Huihui was heartbroken by the dog Dabai, the dog Dalan appeared.
Dalan: "Go back with me."
Huihui: "Okay!"
Dabai: "Wait a minute, I think I can still..."
Big Blue: "No, you can't."
Dog Dalan has a not-so-secret secret. He missed his soul mate, Heihei, and accidentally lost him. So he searched again and again, and finally found Heihei who had changed his color in a world. But it doesn't matter, no matter it is black or gray, it is still a dog and a blue cat, the only cat.
Intention: Love will not change with time, and even death cannot separate those who love each other.
