Do you remember high school? Even if those people just meet you by chance, those things just happen to pass through your life.
It seems that the memory of that time is the clearest and cleanest. Those people and those things may suddenly appear on the way to get off work one day when you grow up. You look at the people coming and going on the road and the orange-red sunset at the end of the street, and suddenly you remember that moment when you and your friend stood in the corridor at the entrance of the classroom, watching the sunset side by side.
It was a moment you wanted to go back to.
You thought of your figures when you were running on the playground, like a spring lightning.
Just like S. H. E sings in "I Was a Boy": "Many years ago, I was a simple boy."
So, let me take you back.
Concept: Those accidental regrets are also beautiful
