When she was five years old, Song Chenxi threw herself in front of her mother and hit her forehead hard against the wall.
She failed to save her mother, but she lost her ability to speak forever.
From then on, the name "Chenxi" became the biggest irony - her world was filled with eternal night.
Transfer student Xia Yeliang came here in the autumn wind. He always walked alone, and the collar of his school uniform was always buttoned to the top.
No one knew that he had just experienced a family tragedy, and no one knew that when he returned to school to pick up books late that night, his heart throbbed violently when he saw Song Chenxi locked in the classroom through the window.
He helped her out, helped her retrieve the textbooks that had been maliciously thrown away, and silently guarded the door when she was locked in the equipment room.
She wrote "Thank you" on a post-it note, and he replied "By the way"; she drew a little sun for him, and he stuffed hot milk into her drawer.
Her aphasia is not a flaw, but a gentle code that belongs to him; his indifference is not nature, but a protective color hiding the wound.
When the morning light meets the cool night, day and night no longer alternate, but embrace each other to form a warm light that never ends.
Purpose: redemption
