Shi Yu transferred to Nancheng due to his parents' divorce. On a rainy night, he bumped into Cen Shi and violently suppressed the gangster, mistaking him for a delinquent.
- When school started, I found out that the other person was actually the genius boy who was number one in grade, and I was forced to become my roommate. Cen Shi armed himself with lighters, earrings, skipping classes and other rebellious behaviors, but Shi Yu noticed something strange from his trembling left hand when solving problems.
- Cen Shi's pursuer bullied Shi on campus out of jealousy, but she taught him a lesson in Taekwondo. After Cen Shi witnessed the whole process, he began to secretly pay attention to this girl who could break glass with one punch but was afraid of the dark.
Unknown corners are full of flowers
When they teamed up to fight off the gangsters outside the school, Shi Yu's left hand was seriously injured while protecting her. He cried for the first time when he carried her to the hospital. In the first snow of winter night, two scarred people clasped their fingers.
[I heard that if you fold a thousand paper cranes a day, as long as you fold a thousand paper cranes, you can bring good luck and happiness to the person you like]
A video of Shi Yu's father cheating on her was exposed, and the whole school insulted her as "the daughter of a junior high school student." Cen Shi was forced by her father to draw a clear line with her in public.
- When Shi Yu was questioning Cen in the rain, he saw his father suddenly appear and be violent. In order to protect Shiyu, Cen Shi deliberately provoked her to leave and bear his father's anger alone, leaving lifelong scars.
- On the eve of Shi Yu's transfer to another school, he found an undelivered paper crane on Cen Shi's desk. Inside the paper crane was written:
"Wait until I become a fire that can light up the night."

- Seven years later, Cen Shi, who had become a firefighter, reunited with Shi Yu backstage at a piano recital.
Shi Yu rushed into the fire to save the trapped children, and Cen Shi tore off the fireproof clothes and carried her out in the flames, like a confession through the sea of fire.
The burn scar on Cen Shi's left arm overlapped with the knife mark on his collarbone, and he completed a two-way redemption in the piano song "Fire and Ice".
- When Shi Yu entered the International Concert Hall, Cen Shi, who was wearing a fireman's uniform in the audience, raised a lighter, and the blue-purple flame illuminated the ring on her ring finger.
