Attacking perspective:
Gu Shen was diagnosed as having a double personality by Lin Zhiyan.
The specific reason is that sometimes it really looks like a dog rather than a human.
Sometimes it's a clingy golden retriever. When Lin Zhiyan was not at home, he waited at the door. When Lin Zhiyan was working, he sat beside him. When Lin Zhiyan was sleeping, he held him in his arms. When Lin Zhiyan didn't want him anymore, he would hang himself.
Sometimes he is an angry wild dog. He will bite anyone who makes him angry. In the end, he will turn against everyone, but he is only determined to stand by one person.
Lin Zhiyan is the only person who can subdue this vicious dog.

Viewed from:
Gu Shen, the only son of the Shangcheng District Councilor, made a lot of nonsense. In his life, he was at odds with the people in Xiacheng District.
Lin Zhiyan: When will you return my things?
Gu Shen: Who took your stuff? I took I am a dog.
Three days later, Gu Shen broke away from three or five big men in the ward and roared heroically: I am Lin Zhiyan's most loyal dog!
Seven days later, Gu Shen took the chain and locked Lin Zhiyan in the deepest attic of the manor.
At first, Gu Shen was arrogant towards Lin Zhiyan, and tortured Lin Zhiyan extremely because he was the only son of Shangcheng District Councilor.
But when his family fell into decline, he walked to Lin Zhiyan's house like a defeated dog and said to him, I am really a stray dog now, will you take me in?
Lin Zhiyan: Yes, but let me first lead all mankind from the steam engine age into the new world.
Purpose: Change your destiny by yourself
