Joss Wayar Sangngern

Round One casts Joss as Zack, a professional boxer, and this is one part he has already tested in a real ring. In 2022 he won the celebrity boxing show 10 Fight 10. Way-ar Sangngern (เวอาห์ แสงเงิน), nicknamed Joss (จอส), is an actor born on 8 March 1996 in Thung Song District, Nakhon Si Thammarat Province, Thailand. He studied at Sarasas Witaed Saimai School and Traill International School, and holds a bachelor’s degree from the Faculty of Communication Arts at Chulalongkorn University.

He started on the other side of the lens. In 2016 he joined Domundi TV in its first generation of content creators, working alongside Zee Pruk Panich, and in 2017 Cleo Magazine gave him its “Love at First Sight” Prize for the Domundi TV channel. He left in 2018, played Safe as a guest in Friend Zone that year, and then landed his breakthrough role as Neo in the GMMTV series 3 Will Be Free (2019). GMMTV has been his agency since 2019.

Steady work followed. He played Pongkul in Game Rak Ao Keun (2019), Ake in Fai Sin Chua (2020) and Safe again in Friend Zone 2: Dangerous Area (2020). He played Kawin, also called Win, in Nabi, My Stepdarling (2021) and Tim, full name Theerapat Theerachaichan, in The Player (2021). In 2022 he played Kayu in Mama Gogo and Bomb in the third story of Good Old Days, a series whose cast shared Best Drama Series at the Asian Academy Creative Awards 2023. He played Zen as a guest in Midnight Museum and the main role of Thann Saengsawang in Loneliness Society, both in 2023.

His breakthrough in BL came in 2025 with My Golden Blood, where he played Mark Amarittrakul, also known as Mark Jensen, opposite Gawin Caskey. The two hosted the JossGawin Invincible Fancon concert in 2025, and their duet “Ever After” from the My Golden Blood soundtrack won an original soundtrack of the year award. They paired up again in 2026 for Only Friends: Dream On, where Joss plays Arnold, who only joins the theatre production once he hears about its cash reward, and they lead Round One, which came together after an earlier project they had signed for was cancelled. He is also in the cast of High & Low: Born to Be High.

Sport runs through his career. Besides the boxing title, he competed in both seasons of the celebrity basketball show 3Fight3 Basket Boy, and in 2025 he became a brand ambassador for Under Armour Thailand.
