Lin Yu, the bright and handsome basketball captain, fell into the eyes of transfer student Shen Zhiyu, who was as cold and fair as the fragile moonlight.
One is a popular king who is impulsive and protects his shortcomings, warm on the outside but pure on the inside, and the other is a sensitive, tolerant, and talented student at the piano. The throb of fingertips touching each other, the ambiguity of sharing an umbrella on a rainy day, and the heartbeat of taking a peek during evening self-study, made Lin Yu repeatedly struggle with obsession and panic - he was afraid that this out-of-control heartbeat was an abnormal sinking.
But the shadow of bullying suddenly shrouded the school, the claws of the evil master quietly approached, and the moment blood stained the school uniform, all attempts to escape were defeated.
The beatings in the back alley, the shock in the piano room, the cold light of the utility knife, the breathless hiding in the abandoned warehouse, the hugging for warmth in the hotel late at night... From the bullying and bloodshed to the attempted invasion by the evil master, from witnessing the murder to being chased crazily by the real murderer behind the scenes, they depended on each other for life and death in desperate situations.
Lin Yu blocked the knife for him and his clothes were stained with blood; Shen Zhiyu broke through the defense for him and ran bravely.
The vicious and perverted half-brother who hides in the dark, the cold, selfish and sin-containing father, the darkness that once pushed Shen Zhiyu into the abyss, are finally completely illuminated by the teenagers with each other's glimmer of light.
From homophobic escaping to life-saving protection, from fearful tolerance to calm love, he is his only salvation in the abyss, and he is the eternal glimmer of light in his darkness.
When the murder case is solved, the villain is brought to justice, and the young people walk side by side in the sunshine, the music of the piano and the basketball collide to create a gentle echo - from the first heartbeat to staying together for the rest of my life, you are my best friend and my glimmer of light.
