Cheng Shu had a piece of rubber, which was small and light, but so heavy that he could not breathe for the rest of his life.
That was Yu An's warmth, the only trace of warmth he had left in this world that refused to dissipate.
Yu An is a wingless bird, falling silently.
Cheng Shu is the person who never has time to say "I am" in his life.
The short story is a full chapter, BE warning, the story is purely fictitious
Intention: Some people are born without wings. It's not that they don't want to fly, it's just that they can't fly.
