Fashion designer Lin Wan harbored a ten-year secret love and sewed her love into 3,000 shirts in an attempt to get closer to CEO Gu Chengze. The family marriage tied them together, but it also made Gu Chengze misunderstand her sincerity. The red wine on the wedding night extinguished her expectations, starting a three-year cold marriage.
Lin Wan was diagnosed with advanced gastric cancer and stopped treatment. She spent her last moments making immortal flower specimens for Gu Chengze, embroidering butterflies all over her wedding dress, and devoted herself to erasing her own existence. As the truth gradually emerged, Gu Chengze discovered that the girl who rescued him in the disaster relief report ten years ago was Lin Wan, and the latest of her design manuscripts collected in his mobile phone was actually a blood-stained medical certificate.
When all the evidence pointed to the truth of that year, Gu Chengze collapsed in front of the autopsy table. The butterfly specimen left by Lin Wan flutters its wings in the glass coffin, freezing this belated awakening and making the sadomasochism between the two an eternal regret.
