Genius Girlfriend (天才女友) has finally arrived on iQIYI, and viewers wasting no time diving into the story have already discovered one thing: keeping up with equations might actually be easier than keeping track of the relationships. Thankfully, beneath all the maths competitions, genius students and emotional glances across the classroom sits a surprisingly warm coming-of-age story where every friendship matters just as much as the romance. If you're wondering who belongs to whom, who secretly likes whom and why everyone seems to solve impossible equations before breakfast, here's the complete relationship chart and cast guide.
Directed by Tian Yusheng and adapted from Su Guangtong's popular web novel, Genius Girlfriend blends youth romance with academic rivalry across 28 episodes. Rather than relying on dramatic misunderstandings every other episode, the drama builds its relationships through years of studying together, growing up together and occasionally staring at maths problems as though they personally started the argument.
At the heart of everything is Lin Zhixia, played by Tian Xiwei, a physics and mathematics prodigy whose IQ reportedly reaches an astonishing 174. Brilliant? Absolutely. Socially smooth? Not even slightly.
Lin Zhixia says exactly what she thinks, often without realising she has accidentally stunned everyone around her into complete silence. She's the type of student who can solve international physics problems but struggles with basic small talk. Ironically, equations make perfect sense to her, while ordinary conversations remain the real mystery.
Her life changes when she meets Jiang Yubai, portrayed by Hu Yitian. If Lin Zhixia represents logic, Jiang Yubai represents warmth. He's popular, cheerful, academically gifted and somehow manages to know everyone in school without appearing remotely exhausted by social interaction.
The pair first cross paths during a problem-solving competition before becoming desk mates at one of the province's top high schools. Their relationship begins exactly how audiences love it: as academic rivals constantly trying to outdo one another.
Every classroom challenge becomes a silent competition, with each refusing to admit the other might actually be impressive. Thankfully, neither of them throws textbooks dramatically across the room. Their rivalry is built on respect rather than unnecessary chaos, making their gradual friendship feel surprisingly natural.
As the story develops, Jiang Yubai quietly becomes Lin Zhixia's bridge into ordinary teenage life. He introduces her to friends, helps her navigate awkward social situations and gently encourages her to open up.
Meanwhile, Lin Zhixia becomes the one person capable of challenging him intellectually without making it feel like a contest. Together they slowly shift from rivals to best friends before romance inevitably enters the picture.
Of course, nothing is ever completely straightforward. Just as Jiang Yubai prepares to confess his feelings during graduation, his family becomes caught up in a fraud investigation, forcing him to leave unexpectedly.
Their story pauses just when viewers expect fireworks. Instead of dramatic declarations, life simply gets in the way—a surprisingly grounded twist for a youth romance.
Years later, fate gives them another opportunity. Lin Zhixia has transformed into a respected astrophysics researcher and university professor, while Jiang Yubai has followed his own successful path.
This time, the pair reunite as research collaborators rather than classmates, allowing their unfinished story to continue from adulthood instead of adolescence. Rather than pretending the years never happened, the drama embraces how both characters have matured while still recognising the feelings they left behind.
The emotional backbone of Genius Girlfriend is not only its central romance but also the friendships surrounding the couple.

Tang Tingting, played by Li Jiaqi, quickly becomes Lin Zhixia's closest female friend. Bright, energetic and endlessly supportive, Tang Tingting provides the warmth Lin Zhixia never really experienced growing up.
Where Lin Zhixia often overthinks, Tang Tingting simply gets on with life. Their friendship gradually teaches the genius student that emotional intelligence matters just as much as academic excellence.
Alongside her stands Jin Baihui, portrayed by Vivienne Tien, another important member of the friendship group. Jin Baihui helps create the safe environment that allows Lin Zhixia to finally feel included. Together with Tang Tingting, she introduces Lin Zhixia to the ordinary joys of teenage life, proving friendship sometimes teaches lessons no classroom ever could.
The boys complete the group's dynamic in equally important ways. Shen Fuxuan, played by Lai Weiming, is Jiang Yubai's closest confidant and loyal companion. Long before Jiang Yubai admits his feelings aloud, Shen Fuxuan already knows exactly what's happening. Every romance apparently needs one friend whose primary job is raising an eyebrow whenever the main couple refuses to admit the obvious.
Duan Qiyan, portrayed by Xia Haoran, represents another key figure within the academic circle. He competes alongside the group during school activities and mathematical competitions while also helping uncover a major cheating scandal that tests everyone's integrity. His presence reinforces that competition does not necessarily prevent genuine friendship from forming.
Meanwhile, Lin Zeqiu, played by Wu Jiakai, reflects the wider pressures facing elite students. His story highlights the expectations placed upon young people studying at prestigious schools, reminding audiences that intelligence alone does not remove emotional struggles.
Wan Chunlei, portrayed by Sun Mengqiu, contributes to the broader school atmosphere by representing the classmates growing alongside the main cast. Although not directly involved in every major storyline, the character helps build the believable community surrounding the central group, making the school's world feel far more authentic.
Together, these characters create a relationship map built less around family feuds and more around emotional growth. Instead of endless rival clans or complicated inheritance battles, the biggest conflicts often revolve around examinations, friendships, future ambitions and quietly hidden feelings. Surprisingly refreshing, really. Nobody is trying to seize a family empire before homeroom starts.
Although family members influence the story, particularly through Jiang Yubai's household crisis, the real family within Genius Girlfriend becomes the friendship circle itself.
Over ten years, the group supports one another through competitions, disappointments, university admissions, career choices and adulthood, gradually becoming each other's strongest support system.
One of the drama's biggest strengths is how naturally every relationship evolves. Nothing feels rushed. Lin Zhixia doesn't suddenly become outgoing overnight, while Jiang Yubai never stops encouraging others despite facing his own difficulties. Their development unfolds through countless everyday moments, from solving equations together to surviving school clubs and research projects.
The chemistry between Tian Xiwei and Hu Yitian is also expected to be one of the drama's biggest talking points. Tian Xiwei's understated performance captures Lin Zhixia's awkward honesty without making her feel emotionally distant, while Hu Yitian brings enough warmth and quiet confidence to make Jiang Yubai an easy character to root for. Together they create a romance based on mutual admiration rather than exaggerated misunderstandings.
Fans' reactions have naturally been mixed, though the overall response has leaned positive since the series premiered. Many viewers have praised the refreshing focus on intelligent characters whose relationship grows through respect and shared ambition instead of constant arguments.
Others have joked that they needed a calculator just to keep up with the physics references, while some admitted they stayed for the romance and unexpectedly became invested in the entire friendship group. There are also viewers hoping the adaptation remains faithful to the original novel, particularly during the emotional reunion later in the story.
Ultimately, Genius Girlfriend isn't really about discovering who the smartest student is. It's about discovering who stands beside you when life becomes complicated, whether that's during a maths Olympiad, a university application or years later when adulthood refuses to follow the neat formulas everyone expected.
If the opening Genius Girlfriend episodes are any indication, audiences should expect heartfelt friendships, believable romance, plenty of academic pressure and enough emotional payoffs to make those long study sessions worthwhile. So, which relationship has become your favourite already, and which character do you think will steal the spotlight as the story unfolds?
