Oat Tharathon Phumphothingam

Tharathon Phumphothingam (Thai: โอ๊ต ธราธร พุ่มโพธิงาม; born January 25, 2000), known by his nickname Oat, is a Thai actor signed to Studio Wabi Sabi. He is best known for playing Daotok opposite Ngern Anupart Luangsodsai’s Arthit in the Fourever You franchise, a pairing known as NgernOat.

Oat’s screen career began young, with a supporting role as Copter across 26 episodes of the series Make It Right (2016) and its 2017 sequel. He later appeared in My Only 12% (2022) as Palm before joining Studio Wabi Sabi.

Oat joined Studio Wabi Sabi’s ensemble drama Fourever You (2024) in a supporting role as Daotok. When the franchise restructured into three couple-focused arcs for Fourever You Part 2, he became the lead of the second arc, The Sun from Another Star (2026), playing a withdrawn art student who has spent his life able to see and hear spirits, a gift he treats as a burden, opposite Ngern Anupart Luangsodsai’s skeptical Arthit.

Beyond his television roles, Oat contributed to the The Sun from Another Star soundtrack, recording the single “Khang Lai” as a duet with co-star Ngern. He is active on Instagram and X under variations of the handle @oattrt.

The road to that lead is unusually long. His first credit, in Make It Right, came in 2016, and the series returned with a sequel in 2017, so he spent two successive years in the same production as a young performer. My Only 12% in 2022 added a second credit as Palm, and only then did he join the first Fourever You series in 2024. Studio Wabi Sabi made that series for GMM25, with a simultaneous release on WeTV; its 17 episodes aired from October 3, 2024 to January 16, 2025, and Daotok appears there as part of the campus friend group around the main couples.

The sequel reorganised the franchise into three arcs built around individual couples, and Oat’s was the second. The Sun from Another Star aired on Wednesdays from March 4 to April 22, 2026, on GMM25 and WeTV, which adds up to eight weekly episodes. Its theme song, “Khang Lai”, is sung by the two leads together, so the pairing known as NgernOat is heard as well as seen.
