About the Gao Xuan in the nineteenth layer of space played by Gillian...

Gao Xuan is a character written by the suspense novelist Cai Jun.

"Extensive, profound and mysterious" was the emotion expressed by his girlfriend Chun Yu when she saw him for the first time.

In the book, he is a descendant of the oil painter Mazzolini, and his family has Italian ancestry. Excellent oil painting. He has superb driving skills and excellent photography skills. He also understands philosophy and psychology. The most lethal thing is his eyes. This is a pair of eyes that can attract any girl. The black eyeballs and pupils appear unfathomable. Maybe this is what ancient books call double pupils. When he smiles, a small dimple appears at the corner of his mouth. With his handsome face and a black windbreaker, he looks like a killer with a cold heart.

Such an introverted and self-isolated genius fell in love with a girl named Yunhan while he was in college. However, due to shyness, he did not reveal his true feelings. His first love, and his subsequent death, made him even more self-isolated. But his talent and intelligence are admirable.

After that, he met Chun Yu, and the two began an unforgettable love.

But unfortunately, Gao Xuan died on a winter night in 2004, leaving Chunyu alone in grief.

Xuan, are you still holding an umbrella and standing in the romantic drizzle, waiting quietly for your returning lover?

The person who plays Gao Xuan in the movie version is Shawn Yue's younger brother, newcomer Xu Zhengxi, who graduated from the Shanghai Theater Academy.
