It follows the original plot line, so most of it is the original plot, except that You Yi is everywhere. Her motto is: Where my brother is, I will be there.
In the accident described by the invigilators, You Yi's heart was damaged and Sheng Xin fell into coma...
When Sheng Xin opened his eyes again, it was not her, but You Yi. Everyone thought You Yi had woken up, but she was the only one who knew that it was Sheng Xin who woke up, and Sheng Xin had a mission.
That day she decided to go abroad first. On the way, she looked back and took one more look at You Yi's brother, then she fainted. When she opened her eyes again, she was in the examination room, taking the chemistry test. Bad news: It's chemistry, which she's not very good at. Good news: the proctor is 009. She and 009 bombed the examination room and returned the identity that had been occupied for a long time to 009.
