BIOGRAPHY

Phemadech Vattanapati (ภีมเดช วัฒนาผาติ), who works as Dome (โดม), is a Thai actor. He has one credit and it is a lead: Jeng in Lost to Light (อยากจะดังหรือยังนะ), across all five episodes.

Jeng is the character the series rests on. His T-POP group has fallen from whatever it once hoped to be to performing children’s songs in mascot costumes, and the other members have walked out. He is the one who stays, and the plot is his attempt to rebuild the group by recruiting replacements. One of the people who arrives is Mai, played by Ratchanon Khajitpornphun, a guitarist concealing his identity and a reason for being there. A second couple runs alongside them: Boss Sithian, who owns the record label, and Bailiu, his former boyfriend, played by Thakrit Patthanaworakit and Prosan Chaivirach.

The series was produced by Ultimate Troop, announced in February 2026 as part of that year’s slate, written by Zaanook Jukkroww Nipitpon Muangsinun and directed by Tonnam Piamchon Damrongsunthornchai. It ran five episodes on GMM 25 on Saturdays from 20 June to 18 July 2026, with an uncut version on iQIYI and an edited version on Ultimate Troop’s YouTube channel.

BLGLFlix editorial view

What makes this debut worth a page rather than a line is the shape of the part. Jeng is not the romantic object of the series; he is its engine. Everything that happens happens because he refuses to let a failing group dissolve, and the romance grows out of a recruitment drive rather than the other way round. For a first professional role that is a lot of structural weight, and it puts him in the same position as several other actors in this catalogue who went straight from nothing to carrying a series.

There is a neat and probably deliberate symmetry in the casting. Lost to Light is about a group of performers trying to make it in T-POP, made by a company assembling its own performers, and the two people at the centre of it had never been on screen before. The show’s subject is the difficulty of getting started in the Thai entertainment business, and it was the vehicle by which two people got started in the Thai entertainment business. Ultimate Troop announced it as part of an annual slate, which is the language of a company building a roster, not commissioning a one-off.

Around those two, the recurring cast is full of established names, Mean Phiravich Attachitsataporn and Gunsmile Chanagun Arpornsutinan among them. That is the same construction as Ash, the Hong Kong BL that launched in August 2026: newcomers at the centre, experienced actors underneath. Two productions in two countries, both first outings for their leads, both spending on support rather than on stars. It looks like a considered strategy for launching people rather than a coincidence.

One thing worth being plain about: this page is mostly about a series, because a series is all there is. He has one credit, no recorded date of birth, no place of birth, no biography anywhere, no IMDb entry and no Wikidata item. The only personal detail on the public record is an Instagram account. That will not be inflated into a life story, and a reader who arrives here should leave knowing exactly one substantial thing about him, which is what he did in 2026 and how much of the show sat on him.

A note on where the information came from, because it matters for anyone checking this page. TMDB records no production company at all for Lost to Light and its one-sentence synopsis pairs the wrong characters, describing Jeng as staying “by the stubborn Boss Sithian” as though they were the couple. Ultimate Troop, the writer and director split, the four-person main cast and the actual pairings all come from the English Wikipedia article. A page built from TMDB alone would have named no producer and the wrong love interest.

FILMOGRAPHY — TV SERIES (1)

TRIVIA

His first professional role is the one the plot runs through. Jeng is the character who refuses to let the group dissolve, so every other storyline in Lost to Light exists because of a decision his character makes in the first episode.

Neither he nor his co-lead had any screen credit before this. Both debuted straight into leads in the same five-episode series.

The series is about the T-POP industry, made by a company launching performers into it. The subject and the purpose of the show are the same thing.

Lost to Light exists in more than one cut. The GMM 25 broadcast, an uncut version on iQIYI and an edited version on Ultimate Troop’s YouTube channel.

Ultimate Troop announced the project in February 2026 as part of an annual slate, which is how a company building a roster talks rather than how a one-off gets commissioned.

The director, Tonnam Piamchon Damrongsunthornchai, appears in the series himself in a special appearance.

The public record on him is almost empty. TMDB holds one photograph, no biography, no date or place of birth, no IMDb identifier and no Wikidata item. The only personal detail available anywhere is an Instagram account.

His nickname, Dome (โดม), is one of the most common in Thai entertainment, which made the duplicate check for this profile unusually careful when it was first created.
