Yu Le always thought that this should be regarded as a story of love but with some regrets. However, the reality is more cruel that this is just her story. He is her imaginary lover, which spans seven years.
I have thought about the scene when they met again many times, seeing each other nodding from a distance, and then gradually moving away with their backs to each other. No matter how bad it is, it's just like the slow motion in the movie. We passed each other and suddenly turned back. Unfortunately, the timing of turning back was wrong, so they all left alone, feeling a little lost.
However, the reality is that Yu Le never met him again, whether on the crowded streets or on the roofs where he had been sheltered from the rain.
