Song Yan, an upstart investment banker, and Lu Xun, a down-and-out painter, once spent the warmest time in a 20-square-meter rental house. Lu Xun said that Song Yan was his light. But a misunderstanding on a snowy night caused Song Yan to tear up the painting and the bond between the two. A year later, when they reunited at the painting exhibition, the diagnosis of advanced gastric cancer revealed Lu Xun's difficulties - he just wanted to spend more time with Song Yan. But it was too late. Lu Xun's departure became Song Yan's eternal regret. Watching the paintings on the wall, he finally understood that missing something is a lifetime.
Purpose: Through the tragic separation of Song Yan and Lu Xun due to misunderstanding, it reveals the fatality of lack of communication and trust in love, expresses the deep reflection on "missing the love due to paranoia, leaving only regret for the rest of the life", and reminds the world to cherish the person in front of you and not let misunderstanding ruin the true love.
