Yingchi has been in Strange Case Town since he was born. He has never left the town, but he left the town when he was 18 years old. Two years later, he returned to the town with an injury. Many people asked him what happened, but he did not remember what happened in those two years, leaving only the figure that appeared in his mind from time to time.
It wasn't until that figure appeared in front of him that he knew that that person had gone through all the obstacles just to see him, stood beside him, and told him, "Long time no see."
Concept: Love is a two-way journey between two people
