Mai Mang turns ordinary days into chaos—a sixty-page report proving morning exercise is unhealthy, a boyfriend hunt sparked by a couple phone charm, selling out her cousin to his crush without a second thought. Yet beneath the madness she glows like a small sun, loving with stubborn, illogical warmth until she quietly reshapes the world around her. Her cousin Xie Jingyuan never recovered from a tragedy six years ago. To outsiders he is ice; in his heart, Mai Mang remains at a golden sunset, eyes closed, counting aloud. School beauty Jing Zhihui listens to his breathing and feels only loneliness—grades, rankings, and futures standing between them. Qi Han hides bruises under his sleeves, dating one girl after another while one person stays fixed in his heart. An original YA romance that weaves sibling devotion, secret first love, and friendships where trust and longing blur together. When lone birds cross in the sky, they feel the air stirred by each other's wings—and learn to walk together until the world ends. Start with free preview chapters on SweetNovel.
