Petrichor isn’t your average Thai GL series. Blending procedural crime storytelling with a slow-burn romance, the drama follows a rookie police captain and a stoic forensic doctor as they work side-by-side to solve a series of seemingly disconnected murder cases. At its heart, it’s a story about justice, emotional wounds, and a love that quietly blooms amid blood and bureaucracy.
Directed with a cinematic eye and backed by Thailand’s most beloved GL couple Engfa and Charlotte (Englot), Petrichor stood out in 2024 not only on social media but also with consistent top national TV ratings—a rare feat for a sapphic series.

Plot
Captain Tul, newly assigned to the criminal investigation department, clashes with Dr. Run, a composed forensic pathologist from the science institute. Their working styles couldn’t be more different—Tul is instinctual and direct, while Run is methodical and emotionally distant.
Each episode features a self-contained mystery, but there’s also an overarching case dubbed “The Rain Killer” that ties them all together. As the pair investigate each crime scene, they face not only pressure from powerful interest groups but also their own emotional demons. Together, they dissect evidence, protect the innocent, and slowly build a mutual trust.
What begins as a functional partnership gradually evolves into something more intimate. In contrast to typical GL tropes, Tul and Run’s love story isn’t about overcoming external rejection but facing internal fears and past traumas. Their bond is natural, mature, and deeply earned.
Petrichor Cast
Charactor
Captain Tul is a principled and bold police officer, whose sense of duty is shaped by a childhood devoid of parental warmth but filled with the protective love of her older brother, Tin. She’s straightforward, emotionally resilient, and driven by a strong moral compass, which often puts her at odds with corrupt systems and ambiguous justice. Tul’s emotional journey intensifies when the very person she admires the most becomes the focal point of her deepest inner conflict.
Engfa Waraha is one of Thailand’s most recognized names in the GL entertainment space. Known for her deep connection with fans and her on-screen chemistry with Charlotte Austin (her real-life GL partner), Engfa’s popularity soared after winning Miss Grand Thailand 2020. With a natural screen presence and expressive emotional delivery, she’s gained a strong following beyond pageantry and into acting.
Dr. Run is a composed and highly intelligent forensic pathologist whose emotional detachment stems from a tragic personal past. At work, she is known for her surgical precision and analytical brilliance, but behind the calm exterior lies a woman learning to let others in again. Her emotional turning point comes when she’s forced to confront long-suppressed grief—adding profound depth to her character arc as she gradually opens her heart to Tul.
Charlotte Austin is a Thai-Australian actress and singer who gained massive popularity through her on-screen and real-life pairing with Engfa. With a naturally reserved but charismatic presence, Charlotte brings a nuanced sensitivity to her roles, often portraying emotionally layered characters. Her charm lies in subtle facial expressions and the intensity behind her quiet moments, which have captivated the Thai sapphic fandom.

Petrichor Review
Review
Petrichor attempts to step outside the stereotypical “lesbian drama” mold. There’s no overused “male fiancé” subplot or tension driven solely by coming out stories. Instead, the drama centers around moral dilemmas, crime solving, and how love grows between two women who are already confident in their identities.
Its greatest strength lies in the emotional integrity of the leads and the show’s quiet commentary on social injustice—from systemic corruption in Thai law enforcement to the societal treatment of sex workers and marginalized women.
That said, some flaws are worth noting:
The investigation segments often lack procedural detail. Many clues are conveniently handed over by Run, making the crime-solving a bit unconvincing.
Some plot twists, especially the killer reveal, feel overly forced. The audience is asked to believe a low-profile character with minimal development is behind it all.
Pacing issues near the end, particularly in dialogue-heavy scenes, dampen the emotional payoff.
Still, despite these shortcomings, Petrichor delivers on emotional resonance and visual quality. The chemistry between Engfa and Charlotte anchors the entire series. Whether it’s justice or love, this story lingers like the scent of rain on concrete.
Best Scenes of Petrichor
The bedroom ring exchange
Instead of a grand wedding, Tul and Run share an intimate moment in their bedroom, quietly exchanging rings before heading out to solve another case. It’s understated, heartfelt, and one of the most genuine depictions of commitment in any Thai GL series.Tul confronting Tin
The emotional climax comes when Tul learns that her beloved brother Tin is connected to the murders. Her breakdown—torn between justice and family loyalty—is one of Engfa’s most powerful scenes, raw and unforgettable.Run’s birthday breakdown
On what should have been a day of celebration, Run is blindsided by trauma that resurfaces. Charlotte’s silent collapse, paired with her cold professionalism cracking, delivers a gut-punch of vulnerability.The “two cats” symbolism
A quiet callback to how Tul first helped Run open up—through caring for stray cats. The metaphor subtly returns in the finale, where the cats mirror their relationship’s journey from guarded strangers to soulmates.
