BIOGRAPHY

Guy Sivakorn Lertchuchot (Thai: ศิวกร เลิศชูโชติ; born August 27, 1992) is a Thai actor with more than thirty-five screen credits since 2016. Born in Surat Thani, he graduated from Bangkok University’s School of Communication Arts with a film degree in 2015, having won the university’s Freshy Boy & Girl competition the year before.

Guy made his acting debut in 2016 as First in the series Kiss, and later that year played Yong in SOTUS, a role he reprised in Our Skyy (2018). Regular work followed through the late 2010s: Bas in Slam Dance (2017), Otto in My Dear Loser (2017), Ohm in Wake Up Ladies (2018), Dr. Oh in Love at First Hate (2018) and Phon in Endless Love (2019). In 2020 he took the role of Dim in 2gether: The Series.

From 2020 his roles included Itt in Tonhon Chonlatee (2020), Ath across eighteen episodes of Khun Mae Mafia (2020), Xia Ah in the twenty-two-episode Irresistible (2021), “Khun” Khunphol in P.S. I Hate You (2022), Kriangkrai in Double Savage (2023), Kitti in The Jungle (2023), Trin in Hidden Agenda (2023), Pong in the Thai Cherry Magic (2023) and Paul in Pluto (2024). He appeared as Jimmy in The Heart Killers (2024-2025) and has continued into 2025-2026 with Dear My Secretary, Memoir of Rati, Hide & Sis, Haunted Mansion and Chasing Love, Chasing Cash. He is active on Instagram and TikTok as @guysivakorn and on X as @SivakornLert.

Before the later run he spent his first years in long ensemble casts. Kiss gave him sixteen episodes as First in 2016, and in 2017 he returned as Yong in SOTUS S and played Curtis in the four-episode U-Prince: Survey. In 2019 he played Touch in 3 Will Be Free, and in 2020 he took Sunny, a brother character, in the six-episode Girl Next Room: Motorbike Baby.

The 2022 to 2024 stretch shows his range most clearly. In 2022 he played a character named Guy in Good Old Days, Yut in Mama Gogo and Decha across the twenty-two episodes of Drag, I Love You. In 2024 he played Thaenkhun Sopharak in the sixteen-episode Law-less and Kop in the film The 4 Danger. His 2025 work included Kawi Krittichayat in the sixteen-episode Dear My Secretary, Sadej Mai in the twelve-episode Memoir of Rati, Chain in Hide & Sis and Khem in Haunted Mansion. In 2026 he followed with Em in Chasing Love, Chasing Cash and Suea Daeng across the twenty-four episodes of The Outlaws.

Every great BL story needs a great supporting cast, and Guy Sivakorn has made a career of being exactly the face you are happy to see around the leads. He was Yong in SOTUS back in 2016, kept Yong going through SOTUS S and Our Skyy, and then played Dim in all three parts of the 2gether story. That is serious loyalty to a character.

What makes him fun to follow is the range around those roles. He has done long runs, like Ath over eighteen episodes of Khun Mae Mafia and Xia Ah in Irresistible, and also drops into shows for a single guest episode, like Jimmy in The Heart Killers. In between he has popped up as Pong in the Thai Cherry Magic, a remake of Yuu Toyota’s Japanese manga, and as Paul in Pluto, adapted from Chao Planoy’s Thai novel. And yes, he once played a character literally named Guy in Good Old Days.

Where to begin? I say go old school with SOTUS for Yong, then skip ahead to 2gether: The Series for Dim. After that, Cherry Magic is a sweet stop to see him in a newer GMMTV remake.
