In the early years of the Republic of China, he and she met by the "Bishui Pond". It was an ordinary encounter, neither stunning in appearance nor unexpectedly embarrassed. The two gradually became friends, and the experiences they exchanged throughout the day gave them a tacit understanding of each other, like a close friend. At first, the two of them were dull and thought that the sudden throbbing in their hearts was the cherishment of like-minded people. Until the feeling became more and more intense, the two of them finally realized that something was wrong. When he saw her coldness, his heart sank. Even though he knew about his long love, he was unwilling to force it; . . The two of them just avoided each other and missed the best moment. Looking back, he was no longer here. She was alone, guarding this long love, dreaming of an empty life for no reason.
