Xia Zixing's youth begins with a cautious, secret crush.
A near-collision in the middle school corridor, a figure leaping across the basketball court: the name Xiao Zihe is a secret she doesn't dare confess, tucked away in her diary. Back then, Chen Fengyang, a basketball-playing boy from the class next door, follows her with a burning gaze, but she never notices. Her heart and eyes are filled with the boy named Xiao Zihe.
Luckily, her secret crush isn't one-sided. The high school breeze brings an answering heartbeat, and Xia Zixing and Xiao Zihe walk hand in hand through a noisy summer filled with cicadas, then enter university together.
Their university days are tender and sweet. Xiao Zihe's words, "I like girls who can play the piano," become the direction Xia Zixing pursues. Starting with no experience, she clutches her sheet music and goes from stumbling through the notes to playing smoothly. In less than two years, she earns her Grade Eight piano certificate, a weighty expression of love she presents to Xiao Zihe.
After graduation, Xiao Zihe puts on a flame-blue uniform and becomes a firefighter who runs toward danger, protecting countless homes and the girl he calls his star. But no one could have imagined that Chen Fengyang would give up his well-paid job abroad and put on the same uniform. He's not there to protect justice. He's there to take what he wants: to steal Xia Zixing and destroy Xiao Zihe.
The flames of jealousy burn more fiercely than the smoke of a fire. Chen Fengyang's relentless pursuit becomes a blade hanging over Xiao Zihe's head.
Until the day of that disastrous rescue.
Flames soar into the sky, and the ruins collapse. At the critical moment between life and death, Chen Fengyang lets go and runs off alone. Xiao Zihe, however, uses his own body to shield the child in his arms. The smoke chokes off his love for Xia Zixing
