WilliamEst
WilliamEst is the pairing of Thai actors William Jakrapatr Kaewpanpong and Est Supha Sangaworawong, both under GMMTV. The studio uses the Thai form วิลเลี่ยม-เอส, William first, and the hashtag #WilliamEst follows the same order.
They were first cast opposite each other in ThamePo: Heart That Skips a Beat, which premiered on GMM 25 on 13 December 2024 with William as Thame and Est as Po. It was William’s acting debut. He is also a member of the group LYKN.
Three further productions followed. In Me and Thee (15 November 2025) the two appeared in supporting roles, William as Rome and Est as Mok, and they carried the same two characters into Peach and Me (11 July 2026). Their second lead outing is You Maniac (เดี๋ยวจะรักซะให้บ้า), which premiered on GMM 25 on 29 August 2026 with William as Dean and Est as Moth.
Outside the dramas they have released the songs “Love Echo” and a cover of “Good Time” (both 2025), and were named Hottest Artist as a duo at the Kazz Awards 2026.
Correction note. An earlier version of this page named You Maniac as the first production the two acted in together. That was wrong: ThamePo preceded it by twenty months. The filmography above is the corrected order.
GMMTV is the only company credited on the pair’s latest series, with no co-producer.
You Maniac lists GMMTV in the studio field and nothing beside it.
A sole studio credit tells a reader where the scheduling decisions sat. The company that cast the pair also placed the series on GMM 25, with oneD carrying it alongside. Ten episodes at 43 minutes each went out from 29 August 2026 to 31 October 2026.
Casting, production and first broadcast all sit with GMMTV, and no outside partner is named at any stage. The ten episodes add up to seven hours and ten minutes.
Four productions in under two years, and the two of them have played the same relationship in three registers: the slow-burn lead pair of ThamePo, a recurring supporting couple carried across Me and Thee and Peach and Me, and then the harder comic setup of You Maniac, where William's Dean has always been wanted and Est's Moth is simply not interested. The refusal dynamic in You Maniac only reads because the audience already knows what this pair looks like when the pull is mutual.
