Heart Sent to Wind Turns to Snow, Love Wasted on Clouds and Moon

Heart Sent to Wind Turns to Snow, Love Wasted on Clouds and Moon Plot:

Su Wanyi poured ten years of devotion into letters sent to the snow-capped mountains, all because Qi Yan—the boy who saved her—said, "Wait for me, the wind will bring the answer." She believed the wind would carry her heart to him, until she saw Qi Yan embracing her best friend under the moon. The truth hit her like ice: the "promise" was Qi Yan's final vow to his dying sister, and every letter of hers had been locked in a drawer as his sister's relic. Just as she burned all the letters to end this love, Qi Yan rushed into the fire with snow-stained letters: "I knew it was you all along! Those letters the wind took, I've been picking them up in the mountains for ten years..." In the snow, his frostbitten hand wiped her tears, but she didn't dare ask: is this belated response true love, or a replacement for his "sister"?
