People never learn to cherish until they lose it. Just like when Liang Weixi lost a girl, he always missed the unpleasant scream, but every time he looked at the empty basketball court, the girl was no longer there. People always regret giving up when they leave. Just like when Qin Huaijing came to the south, he began to miss the heavy snow in the north. Every time he recalled the flying snowflakes, the smile on the corner of the boy's mouth would appear in front of his eyes. If we could go back to the heavy snowfall of that year, and we met under the dim light, would we gently speak the words from the bottom of our hearts instead of passing each other and letting the snow in our hearts bury all possibilities.
