Dong Si Yi

When a VR game conjures up a realistic dream, youth restarts for a man who returns to his schooldays in a journey of self-healing. Ten years after high school, Lin Shang He, Cui Zhen Yan, and their close friends think of a way to help Xia Shi get over the psychological trauma that he continues to suffer from since Ye Sang Yu's accident. A game takes Xia Shi into the world of virtual reality back to the time when he was a student, thus allowing him to unravel the mystery through his memories to recover a friendship that has been lost.

Yang Yi is a free-spirited girl who's homeschooled by her father, who raised her on his own after her mother passed. He homeschooled her while allowing her cousin, who is her best friend, to attend his school (He's the headmaster), out of fear of his daughter being ill-influenced, or harmed. On her birthday, Yang Yi finds her friend Ye Qing washed up on the beach, and brings her to the ER, only to find out she's in a coma. She then transfers to the all girls school as a boy to find out what brought her friend to suicide.
