On 10 December 2019, Singapore's mm2 Entertainment and Taiwan's CaiChang International and Good Films Workshop announced the series. It was based on the novel of the same name by Taiwanese novelist Xing Zi. The series would be directed by Donnie Lai, produced by Rita Chuang and choreographed by Jimmy Hung, with Kai Ko, Wang Po-chieh, Sonia Sui, Kuo Tzu-chien and Pipi Yao starring in lead roles.[5][6] The series would consist of six episodes and the production cost of the first season was expected to exceed NT$180 million, making it the most expensive drama to be produced out of Taiwan.[7][8] A pilot episode was planned to film in 2020, before the distributors were announced, and scheduled to be released in 2021.[8][9] Production was ultimately postponed due to COVID-19.[10] In November 2022, Hsueh Shih-ling, Buffy Chen and Johnny Yang were added to the cast.[11]
Filming
Principal photography began on 14 November 2022, in Keelung, Taiwan.[12] On 27 December 2022, a drone failed and crashed in front of Kai Ko while filming a close-up. The drone's blade sliced Ko's cheekbone and resulted in severe facial injuries. Ko was hospitalized and required 30 stitches.[13][14] Production was suspended after the accident and resumed in 11 January 2023.[14][15] Filming was wrapped on 5 March.[16]
Release
The series was scheduled to premiere on Netflix in 2023.[17]
