Regarding this story, I don't know what kind of mentality I had in writing it. Maybe it was due to impulse... I just suddenly realized that my high school, college, and youth were not as vigorous as I imagined when I was young, and they will never be passionate in the future. But I am not willing to do this. Reality cannot repeat itself, so I will create a fictional world and let the protagonists in the book experience different lives, grow up in different events, learn to love, and learn to be loved... At the same time, they also experience separation and loss...
