On an isolated island in Shanghai where neon lights and blood intertwined, she fell into the wind and dust like a butterfly with broken wings. The sinister cage of the ex-husband, the bloody guardianship of the underground lover, and the cross-ocean pursuit of first love - the three-way struggle is tightened in the rain. When the sapphire lapel pin reflected the gunfire and the crabmeat dumplings were still stained with tears, she finally understood in the morning light of the concession church: some love is honey wrapped in arsenic, and some love is a lighthouse hidden in the reef. Where the dust of the troubled times has settled, an edelweiss quietly pierces the frozen soil.
