When Youan was seven years old, his childhood sweetheart Yan Zheng disappeared on the first day of summer vacation.
The family's hair salon was closed, and the Yan family who adopted her were worried.
She gradually fell asleep after lunch, and a purple-eyed cat appeared in her dream. It was held hostage by men and women in period costumes from the TV series, sniffing around the mountains, rivers and streams.
She hadn't had such an interesting dream for a long time. She wanted to take a closer look at the cat, but found that it was the lost Yan Zheng who didn't like to talk to her.
After saving him, Youan's life suddenly changed.
Intention: Exercise and work hard every day
