The sky when I was eighteen or nineteen seemed bluer and purer than it is now. I remember that at that time, the valley was full of camellias. Every time I recall it, I seem to be able to smell the fragrant and cool air of early spring.
In fact, I don't dare to recall it. When I recall the first half, I smile happily. The two of them didn't speak at that time and only glanced at each other. They could see the smile overflowing from each other's eyes, but what couldn't be avoided was the second half. I dare not recall or think about it.
Those are the past that can never be returned to.
