Ryujin Tinnapat Tusnytraitep
BIOGRAPHY
Ryujin Tinnapat Tusnytraitep (Thai: ทินภัทร ทัศนีย์ไตรเทพ; born 10 January 2006 in Bangkok) is a Thai actor working under DOMUNDI TV. Every credit on his record is a Mandee Work production, and three of the four have been carried by ONE 31.
He first appeared on screen as a contestant in DMD Friendship The Reality, the competition that began on 17 December 2023 on ONE 31 and iQIYI International. He features in ten of its eighteen episodes, the fourth-highest count of anyone on the show.
His first scripted role was In, a single-episode part in the boys’ love series Your Sky (กี่หมื่นฟ้า), which ran fifteen episodes on ONE 31 between 17 November 2024 and 19 April 2025. He is also billed first as Euro in 20 Lists (ลิตส์นี้มียู), a one-episode DoMunDiTV and Mandee Work pilot that carries no announced release date.
His largest role so far is Renji, full name Jirapahat Itthiphongwarin, in Mr. Fanboy (รักสุดใจนายแฟนบอย). He is credited in all twelve episodes and billed fourth. The series began on ONE 31 on 29 August 2026 and is still airing.
BLGLFlix editorial view
His career is usually dated from Mr. Fanboy in 2026. He has in fact been on screen since December 2023, and the two credits in between are the ones that explain how he got there.
What the full record shows is a pipeline. DMD Friendship The Reality is a competition run by the company he is signed to; the contestants who came out of it are the actors now filling the company’s boys’ love dramas, and Mandee Work has produced every single thing he has been in. Patji Jirachart Buspavanich, who was the most-featured contestant on that same show, appears alongside him in all four of his credits, including the unaired pilot.
The same structure appears in Taiwan. The five top-billed actors of the 2026 Taiwanese BL Smile After Tears all came out of one season of the survival show Atom Boyz, and the drama is made by the survival show’s own production company. Two countries, two unrelated companies, one model: run a competition, build an audience around a cohort, then cast that cohort into the romance. It is worth naming because it changes what a filmography means. When four credits share a producer, the shared producer is the career, and reading the list as a series of independent castings misses the point entirely.
