"Chengyu" means becoming a treasure
You are the only treasure I polished in the ruins
Xu Chengyi and Ji Yu, two children who grew up in hardship, both lost hope in life. Fortunately, someone took them to see the meaning of life and the beauty of the world.
Each other's salvation and companionship allow them to say "you and me" to each other
Even if one day you and I turn into mountain soil and dust in the air, there will still be a voice telling you "I have always loved you."
