I can't help but look back at that hot and long summer.
That is the bitterest and sweetest time in a girl's youth.
The short-lived joy is ultimately in vain.
Later I slowly understood that the most gentle tragedy in the world is probably,
Happiness will always be trapped in memories.
If I could go back in time, I would still meet that boy.
It's just that I will never like him that passionately again.
——Reminiscent of that first love with this book
Concept: Memories are always bittersweet
