Yifan: "I still remember that when I was a child, I drew a shadow once, but in the end I ended up drawing a fish."
Yifan took out a photo of himself from his bag and gave it to Mingzi.
Yifan: "This is called 'missing fish'".
Akiko (smiling): "Why do they call it that, the fish disappears? It's a strange statement."
Yi Fan: "I'm just afraid that one day I will suddenly disappear without a trace for no reason, and you will never see my shadow again... If one day I borrow your wings to fly, I don't think I will be sad..."
So, the fish disappeared.
