“You think you're the one falling. But it's me, the one who's been watching the direction you fall in all along.”
Su Nian, twenty, is a campus radio host who always smiles like a little sun. No one knows that this girl, who tells others to “be happy” every day, has lived alone for eight years since her parents divorced. Her only secret is “Long Night,” the account that posts on the forum late at night. She sends him a warm private message every day, though he never replies.
Lu Yanzhou, twenty-one, is a prodigy in the architecture department, always silent as an island. Born into an elite family, he is being suffocated by his father's expectations. When he can't sleep at night, he uses the account “Long Night” to write down all the feelings of falling that he cannot put into words. Then one day, an ID called “Little Sun” starts leaving comments: “It's sunny today. Did you see it?”
He doesn't know she's the girl with the warm voice from the campus radio station.
She doesn't know he's the young man she once met on the rooftop.
And so begins a story of pretending to pass by...
He quietly remembers her favorite milk tea. On the radio, she says, “This is for everyone who can't sleep.”
She doesn't know the senior she keeps “running into” is the “Long Night” she's been secretly in love with for a year.
He doesn't know the girl who messages him every day is pulling him back from the abyss.
Then one late night, the radio station malfunctions, and her private confession is broadcast to the whole campus.
“To ‘Long Night’: You said you were falling. But did you know that even falling is my salvation?”
The whole campus is in an uproar.
In the darkness, he sheds a tear for the first time.
