When Song Qinghe was ten years old, he accidentally fell into someone else's house from the wall. He looked up at Lu Congwei who was expressionless, and wondered if the sky and the earth could make me disappear from him in the next second. When Song Qinghe was seventeen years old, he was sitting on a plane, staring at the single photo on the back of his phone, wondering if he could return to him if he tried his best like Lu Congwei did.
Concept: A growth story in which the protagonists meet and reunite again.
