Premise

The heroine, Luo Feifei (洛菲菲), is an intern at a hospital in the 21st century with what the show calls a "Mercury retrograde" (水逆) constitution, internet slang for chronic bad luck. On her way to a fan meeting for her idol, she has an accident just as a meteor shower of the Serpent Bearer (蛇夫座), an event said to occur once in a century, appears in the sky, and she is transported to the ancient kingdom of Huangdao (黄道国).¹⁰^•¹¹

Huangdao is governed by astrology: every thousand years, rulership rotates among the owners of the twelve constellations. At the time of her arrival, the Capricorn star lord Beitang Yi (北堂羿) has just succeeded as emperor, and his Beitang family holds unrivaled power, including the Pisces star lord Beitang Tang (北堂棠) and the Aquarius star lord Beitang Moran (北堂墨染), the imperial uncle and the kingdom's foremost beauty.⁵ The emperor looks exactly like Luo Feifei's modern-day idol, and she also meets Bai Wuchen (白无尘) and the tracker Chu Shengnan (楚胜男) in her early misadventures.¹¹^•³

Her arrival upsets the kingdom's balance. By fate she becomes, in the synopsis's words, the most miserable time-travel heroine ever and inexplicably a weak "big villain," clashing comically with the twelve star lords while developing a love-hate relationship with the emperor, declaring "This emperor, I want him" (这个皇上我要了), the phrase used as an alternative title.⁵

Story development

As the season progresses, Luo Feifei's identity as the master of the Serpent Bearer constellation, the thirteenth sign outside the twelve, is revealed, and attacks turn against her. The three Beitang masters protect her and uncover a mystery about a rebellion of the Serpent Bearer constellation a thousand years earlier, with a conspiracy behind it. To save her, Beitang Moran announces a wedding despite the Empress Dowager's opposition, and the triangle among Luo Feifei, Beitang Yi, and Beitang Moran escalates to the national level. In the end Beitang Yi confronts the world to clear her name, the Serpent Bearer clan is vindicated, and Luo Feifei is restored as the thirteenth star lord of Huangdao, though a "bloody storm" is hinted at for the second season.⁶

Production and cast

The drama was produced by Wajijiwa, the agency behind X Nine, whose members fill most of the male roles: Gu Jiacheng, Wu Jiacheng, Xiao Zhan, Peng Chuyue, Chen Zexi, and Yan Xujia, joined by actresses Xie Lintong and Song Nanxi and a special appearance by Wang Yu.²^•⁶ Season 1 aired on Tencent Video three nights a week, Wednesday through Friday at 20:00, with episodes of about 30 minutes listed in the schedule.³ The series is noted for folding modern internet slang, fan culture, and zodiac astrology into its fantasy costume setting.⁸
