The two begin as rivals, and the situation changes when Sheng Wang's father plans to marry Jiang Tian's mother, making them stepbrothers who must live under the same roof while an unexpected attraction grows between them.<sup>[4](https://www.tvmaze.com/shows/78922/the-on1y-one)</sup><sup> • </sup><sup>[3](https://www.iq.com/wiki/zh_tw/album/2ge4shuunbp)</sup>\n\nThe title refers to the phrase \"a certain someone\": the iQIYI synopsis explains that the two develop a deep relationship and become \"the only one\" engraved in each other's hearts, the \"某某\" of the Chinese title.<sup>[3](https://www.iq.com/wiki/zh_tw/album/2ge4shuunbp)</sup> At a September 2024 press event, director Liu Kuang-hui said the two characters of the title, meaning \"a certain someone,\" and the original novel moved him, asking rhetorically who does not have a \"某某\" in their life.<sup>[5](https://www.mtv.com.tw/news/newsdetail/11187)</sup>\n\n### Season 2\n\nThe first season ends before the central relationship fully develops, and continuation became the main open question for viewers. In September 2024, director Liu Kuang-hui said the script for a second season was complete and urged fans to ask the production company for it, saying the decision came down to investment and fan response.<sup>[7](https://dramapanda.com/2024/09/the-on1y-one-director-reveals-why-no-promotion-teases-season-2.html)</sup>\n\n## Production and cast\n\nLiu Kuang-hui directed the series; he had previously directed the 2020 film *[Your Name Engraved Herein](https://www.edgepedia.org/your-name-engraved-herein)*, and reviews of *The On1y One* repeatedly connect his visual approach in the two works.<sup>[3](https://www.iq.com/wiki/zh_tw/album/2ge4shuunbp)</sup><sup> • </sup><sup>[6](https://www.thereviewgeek.com/theon1yone-s1review/)</sup> The leads are Liu Dong Qin, known for *Only for Love*, as Sheng Wang, and Benjamin Tsang, known for *The Pig, the Snake and the Pigeon*, as Jiang Tian; both took leading roles in a drama for the first time.<sup>[7](https://dramapanda.com/2024/09/the-on1y-one-director-reveals-why-no-promotion-teases-season-2.html)</sup><sup> • </sup><sup>[8](https://www.cinemart.co.jp/article/news/20240913009481.html)</sup> The supporting cast includes Lu Tingyu, Samuel Ku, Yan Yu-lin, Tuan Chun-hao, Jennifer Hung, and Yao Ai-ning.<sup>[9](https://leisurebyte.com/the-on1y-one-review/)</sup>\n\nAt the September 2024 press event, Tsang described the pressure of his first leading role, saying he lost 5 kilograms during filming, and spoke warmly of his working relationship with Liu Dong Qin, saying their off-screen dynamic resembled the one in the drama.<sup>[8](https://www.cinemart.co.jp/article/news/20240913009481.html)</sup> Liu Kuang-hui also highlighted the screenwriter's playful dialogue, including a line in which the two leads, hiding in a wardrobe from a parent, ask whether they can \"come out of the wardrobe now,\" a pun on coming out.<sup>[5](https://www.mtv.com.tw/news/newsdetail/11187)</sup>\n\n## Release and distribution\n\nThe series premiered on 22 August 2024 with two episodes, then released one episode each Wednesday and Thursday, ending on 26 September 2024 after 12 episodes.<sup>[1](https://world-of-bl.com/index.php/Taiwan/TheOn1yOne)</sup><sup> • </sup><sup>[9](https://leisurebyte.com/the-on1y-one-review/)</sup> It streamed globally on Netflix, iQIYI International, Viki, WeTV, and [GagaOOLala](https://www.edgepedia.org/gagaoolala).<sup>[2](https://tv.apple.com/br/show/the-on1y-one/umc.cmc.26x22ggh7g0bhdk79jzhzu745?l=en)</sup> According to the director, the production was initially sold only to Netflix Taiwan, and the team had to arrange distribution on other platforms for markets outside Taiwan; he also said there was little promotion before the premiere and encouraged fans to spread word of the show.<sup>[7](https://dramapanda.com/2024/09/the-on1y-one-director-reveals-why-no-promotion-teases-season-2.html)</sup>\n\n## Reception\n\nThe drama drew high audience scores on international platforms: 9.0 on IMDb and 9.8 on iQIYI International, figures the cast and director cited at the September 2024 press event.<sup>[5](https://www.mtv.com.tw/news/newsdetail/11187)</sup> Critics responded positively to its pacing and direction. The Review Geek called it a slow-burn character study carried by Liu Kuang-hui's visuals, scoring the season 8 out of 10 and praising both leads across the 12 episodes.<sup>[6](https://www.thereviewgeek.com/theon1yone-s1review/)</sup> Leisurebyte gave the opening episodes a rating of 4 out of 5, noting the chemistry between the leads and the show's handling of the stepbrother premise.<sup>[9](https://leisurebyte.com/the-on1y-one-review/)</sup>\n\nReception among some readers of the original novel was less favorable. A reviewer on Abstract AF! criticized the ending, arguing the 12 episodes stop at the story's turning point and read like a first part of a longer story.<sup>[10](https://abstractaf.in/the-on1y-one-review-slow-burn-that-ends-before-it-begins/)</sup> Coverage of fan discussion noted criticism from some mainland Chinese viewers of the casting and of plot changes from the novel, while the series found its audience through platforms outside the mainland.<sup>[7](https://dramapanda.com/2024/09/the-on1y-one-director-reveals-why-no-promotion-teases-season-2.html)</sup>\n\n## References\n\n1.
