Jiang Zhimian is a painter, but he imagined a boy in his dream. The boy's name was Xu Nansong. Then he appeared in every Jiang Zhimian's dream. Gradually, Jiang Zhimian believed that Xu Nansong was real.
In the dream, they fell in love, and Jiang Zhimian said to Xu Nansong, "I want to draw you in my painting."
She was in the studio with a pen, but she couldn't draw Xu Nansong's appearance. The paper on the ground was crumpled into a ball. Jiang Zhimian entered the dream again, and Xu Nansong never appeared. In the dream, Jiang Zhimian looked at the place where they had been, but there was nothing around him.
Jiang Zhimian woke up and wrote "Xu Nansong, where have you been" with a black pen on a piece of paper and went downstairs to continue working. At 1:30 in the morning, Jiang Zhimian returned to the studio to pack his things and go home. When he picked up the note, he got a reply, "Amian, I am just a figment of your dream, not a real existence. Amian, take care of yourself."
Concept: The person you dream about cannot be real, because it is just a dream
