A long time ago, a playful deer left the forest chasing butterflies. When it suddenly turned around, it discovered that its former home had disappeared and it was wandering alone in the open grass. It was at a loss what to do.
The butterfly couldn't bear to see the lonely deer, so it flew to it and guided it back to its home. The deer finally returned to the forest, but the butterfly lost itself.
"Hey, Dai Minghao, the story is over,... Are you really listening?"
"Well, I've been listening."
"What do you think?"
"The ending is not good. If I were that deer, I would follow that butterfly and accompany it to the ends of the earth."
