When she was seventeen years old, Su Nian received a diagnosis of terminal bone cancer and a "bucket list" that she did not dare to hand to anyone.
She chose to hide it, smiled and said to everyone, "I'm fine."
Xin Si Nian is a young man who can't say nice things, but he starts stuffing warm babies into her drawer every day, gives her a unique breakfast, and sends her home rain or shine.
He said: "What I did has nothing to do with you."
Su Nian pretended to believe it, and Xin Si Nian pretended not to know.
At the tail end of their youth, they conspired to tell a grand lie - one said I love you with silence, and the other said it doesn't matter with a smile.
But he didn't know that the girl had already known his pretense.
She didn't know that he had been standing in the corner where she couldn't see for eleven days.
When the last locust leaf falls, when the countdown comes to an end - how will that young man who never talks about love face this farewell that already knows the outcome?
Cold and sensitive boy × cheerful and sober girl
Concept: A girl with only half a year left to live pretends everything is normal with a smile, and a boy who never speaks of love clumsily guards her lies with silence.
