Max Kornthas Rujeerattanavorapan

Max Kornthas Rujeerattanavorapan (Thai: แม็ค กรธัสส์ รุจีรัตนาวรพันธ์; born October 25, 1993) is a Thai actor, model, and television host signed to Domundi TV. He is one of the most consistently employed supporting actors in Thai BL, with credits stretching from Why R U? in 2020 to four separate 2026 productions.

He was born in Bangkok and came to acting sideways, studying civil engineering at King Mongkut’s University of Technology Thonburi rather than taking a performing-arts route. He made his screen debut in 2017 with a guest part in Diamond Eyes, but the career only took hold in 2020, when he played Dew in Why R U?: The Series.

From there he became a fixture of the Domundi roster: Sun in Y-Destiny (2021), Titan in Close Friend (2021), and the role he is best known for, Yi (Phayak Chatdecha Chen) in Cutie Pie (2022), which he carried through to Naughty Babe (2023) as a lead. He also appeared as Thai in Two Worlds (2024), Thorn in Zomvivor (2025) and Sun in Suntiny (2025).

In early 2022 he changed his given name from Saran to Kornthas following consultation with a Buddhist monk, a common practice in Thailand. Older credits and database entries still carry the previous name, which is why he appears under both and why his filmography is easy to split in half by mistake.

2026 has been his densest year: Pen-neung, Jay’s best friend, in Payback; Lalit in ChermChey; X in Duang with You; and Song/Sam Traiphop Adisuan in Your Third, his first outright lead of the year. His Domundi work also extends to hosting, on programmes including DMD Friendship The Reality. On BLGLFLIX he is currently attached to two titles: Payback, where his role is a guest appearance, and ChermChey, where he is supporting cast.
