BIOGRAPHY
Kornnaphat Sethratanapong (Thai: กรณ์นภัส เศรษฐรัตนพงศ์; born May 27, 2002), known by the nickname Orm, is a Thai actor and model signed to Channel 3. She plays Sanitada “Earn” Phongpipat opposite co-star Sirilak Kwong in the 2024 GL series The Secret of Us, a breakout role that made the pairing known to fans as “Ling and Orm.”
Born in Bangkok, she attended Wattana Wittaya Academy and Panyarat High School before completing her secondary education through the English-ASEAN program at Srinakharinwirot University Prasarnmit Demonstration School. She holds a Bachelor’s degree in Economics from Srinakharinwirot University and is currently pursuing a Master’s degree in Social Communications at the university’s College of Social Communication Innovation. She made her television debut in 2019’s Hotel Stars before signing with Channel 3.
In 2021 she joined the cast of Game of Outlaws on Channel 3 as Anya Ruangsuradecha. The crime drama ran for nineteen episodes from 28 October to 30 December 2021 under director Chatchai Plengpanich for Metta and Mahaniyom, and it followed two sisters who train as police officers to avenge their father.
The Secret of Us arrived in 2024 as an adaptation of a novel by Meenam, directed by Saratswadee Wongsomphet. It ran for eight episodes on Channel 3, YouTube and Netflix between 24 June and 12 August 2024, on Monday nights. Sirilak Kwong plays Fahlada, a dermatologist at her family’s hospital, who meets her ex-girlfriend Earn again two years after an abrupt breakup. Earn tries to rebuild what they had, and Fahlada slowly finds out why Earn left. The series won Masterpiece of the Year at the HUB Awards 2024 for both leads, and its other honours include Best GL Series at the Y Entertain Awards 2024 and Series of the Year in the GL category at the Thailand Box Office Awards.
Following the success of The Secret of Us, her subsequent credits include Only You (2025), a fourteen episode series on Channel 3 and Netflix that aired on Fridays from 18 July to 17 October 2025. She plays Sasina “Ayla” Ruengkhunakhon, an idol singer who hires a private security firm after threats against her and finds it run by Tawan, a woman she has not seen for eight years. The director, Saratswadee Wongsomphet, is the same as on The Secret of Us, and Sirilak Kwong again plays the other lead.
She won the Most Popular Young Girl Award at the 2025 KAZZ Awards, and The Secret of Us was recognized as one of the year’s best GL productions at multiple Thai entertainment awards ceremonies. In 2026 she and Kwong are both in the cast of In Love Forever, with Orm as Peeracha.
Orm went from a 2019 television debut to a leading GL role within five years.
Her first screen credit was Hotel Stars in 2019. In 2024 she led The Secret of Us as Sanitada Phongpipat, opposite Sirilak Kwong.
Her degrees run in a different direction from her screen work: Economics at the bachelor’s level, then Social Communications for the master’s.
Her timeline shows two kinds of continuity. Her studies stay inside one institution across levels: the English-ASEAN programme at the Srinakharinwirot University Prasarnmit Demonstration School, then the bachelor’s in Economics and the master’s at the same university. Her screen work, meanwhile, moves from a 2019 debut to the lead in 2024 at the age of twenty two. The 2025 KAZZ Awards then honoured both leads of the series in different categories, the Most Popular Young Girl Award for her and Sao Wai Sai of the Year for Sirilak Kwong.
In my view, the detail that stands out is that The Secret of Us and Only You share a director and both leads. It lets you compare how Orm plays a woman who broke off an affair and ran away in the first series with an idol singer under threat in the second. I would start with The Secret of Us, because it is only eight episodes, and move on to Only You afterwards.
