Saying goodbye to the past, Yu Daisi just wanted to make handmade jewelry every day and earn money to support herself. She originally wanted to live a peaceful life in the future, but who knows, a "Bodyguard Recruitment Notice" completely made her life even if she didn't want to have troubles. The childhood memories of youthful beauty and sudden misfortune, the former Jiao Mufeng; now the dull, comfortable and sunny exciting college life, now Shen Jiyang; later, the ups and downs of life development in which he strives to make progress and learns everything, later Come Chu Linfan... Every person around Daisy, every life encounter, every emotion, every love and dedication has left a deep imprint on Yu Daisy's heart. She interweaves everything in the ribbon in her hand, wrapping it with thread and gluing it together. Butterfly knot, love, hate, hurt, pain, regret, helplessness! The wind rises and the silk falls, and the sails rise at dusk. Mu Feng said that he had never stopped loving Daisy and would always make glue sticks for ribbons; Jiyang said that he was grateful to Daisy for liking him, but he wanted her to know everything; Lin Fan said that he was grateful for Daisy's efforts and would give her everything she wanted. Daisy didn't understand why Mu Feng disappeared when he should be by her side the most; Daisy didn't understand why Shen Jiyang chose to refuse when she mustered up the courage to face her true feelings; Daisy didn't understand why Chu Linfan was willing to help her regardless of the consequences. Were the knots in the butterfly and the knots in Aunt Xiaodie's heart untied one by one after she ended her life? Or is it that the so-called love and the so-called love knot are tied in the hearts of these children of the next generation?
