At twenty-eight, Yu Xueheng was gentle and steady, having spent half his life following the rules. But when a friend asked him for help, he took on the responsibility of looking after sixteen-year-old Ye Langlang. At the time, Ye Langlang was in the bloom of youth, with bright, delicate features and a clever, mischievous nature. She had all the innocent, carefree charm of a girl her age, and the moment she entered Yu Xueheng’s life, she disrupted the peace and stability he had known. As her temporary guardian, Yu Xueheng initially cared for her with the tender patience of an elder, indulging her lively, impulsive ways and looking after every detail of her daily life. But as they spent each day together, an unspoken affection gradually filled his eyes, and his concern for her quietly became an inescapable tenderness.
