Slow build, open ending.
Perspective 1: She and he grew up together. She considered herself to be the peony among flowers and never looked down on any woman. However, she forgot that peonies are too bright and some men think they are too tacky.
What he loves is the elegant chrysanthemum. She didn't understand it at first, but later she realized that chrysanthemum is "there will be no more flowers after it blooms."
On the day she got engaged to him, because someone accidentally fell into the fountain pool, he picked up that person and abandoned her in the crowd of guests...
Perspective 2: She broke into his world in her prime, bringing breeze and fragrance of flowers. He cared for her to grow up, thinking that actions were proof of deep love, but he didn't expect to miss her again and again.
On the day she left, he sent her to the airport. He suppressed his bitterness and asked without giving up, "Can't we start over?"
She didn't answer him, and walked into the crowd with her suitcase.
