Shen Xingwan thinks Gu Yanzhou was born to be her nemesis.
He cuts off her internet, signs her up for an Olympiad math class, and mocks her in public for failing math. The whole school knows the young master of the Gu family and the heiress of the Shen family are sworn enemies.
Then, on sports day, they trip and fall, waking up in each other's bodies.
In Gu Yanzhou's body, Shen Xingwan talks back to teachers, kicks bullies, and publicly turns down a blind date. It's exhilarating.
In Shen Xingwan's body, Gu Yanzhou tears into her fake-sweet best friend. Wait, that "good friend" of hers has been badmouthing her behind her back?

Shen Xingwan: Are you insane?
Gu Yanzhou: Hold my hand.
Swapping bodies isn't scary. What's scary is that she suffers a breakdown from insomnia in his body, only to discover that he can only fall asleep by listening to her recordings every night.
His phone has an encrypted photo album filled with pictures of her from childhood to the present. The folder is called "Sleeping Pills."
All those times she thought he was "picking on her" were just his clumsy attempts to protect her.
But before she can feel touched, she discovers there's more: he drove away her unwanted suitors, secretly dealt with her problems, and has been in love with her since the second year of middle school.
He never hated her.
He can't live without her.
[System notification: Once all missions are completed, the System will disappear forever.]
Shen Xingwan looks at the voice that has accompanied her all this way and suddenly doesn't want it to leave.
--Gu Yanzhou, how much have you been hiding from me?
--Everything. But you'll find out.
