Love in youth is always unreasonable, and love in youth is always unexplainable.
This is a memory about youth, a young man's self-growth, and a love story that spans time, life and death.
When a boy who is usually taciturn but actually has a delicate mind meets a girl who is usually active and cheerful but actually has a forced smile;
When Bu Yu, who was used to being alone and not good at socializing, met Wu You, who was seriously ill and longed to make friends.
They met at the best age, and due to various "coincidences" and "accidental encounters", they began to grow from acquaintance to acquaintance, and then from the transformation of relationship to the slow closeness of two hearts.
But just when he was about to pour out his heart to her, an unknown disaster was quietly approaching... And when everything settled, the love that had not been spoken ten years ago was actually responded to ten years later.
