At the birthday party of ten-year-old Meng Yanchen, Gu Nanzhi appeared holding a specimen of a blue swallowtail butterfly. The agile figure and the lines on the wing tips became an obsession that he had hidden in his heart for many years.
Later, when he was in high school, Gu Nanzhi went abroad with his family and his childhood friend Yang Cheng. Before his youthful feelings could be revealed, they were crushed by Yang Cheng's betrayal. Frustrated, she returned home alone and unexpectedly reunited with Meng Yanchen, who was now the helmsman of the Meng family.
The boy who used to watch her silently has now become her most solid support. Meng Yanchen never mentioned her past feelings, he only reminded her when she was confused, stood up when she was entangled by her old people, and when she tried to close her heart, he slowly melted away her defenses with his gentleness day after day.
From the startling glimpse when she was eight years old, to walking side by side as an adult, Gu Nazhi finally saw clearly that the companionship under the Meng family's roof had long gone beyond ordinary comfort. It was a deep love that spanned time, and it was also the answer for her to get over the pain and embrace love again.
