InnOngsa is the pairing of Thai actors Jakkrasin Atsavatanachai (Inn) and Theethuch Khummuang (Ongsa), both working with the One31 network. One31 introduced them together under the Thai form อิน-องศา when it announced the historical BL series The Edge of Horizon (อรุณรุ่ง) on 18 June 2026.
The two had never acted opposite each other before. One31’s announcement described the casting as their first time as a pair, and the series was built around them: Inn plays Phopthee, a commoner and the son of the palace wet nurse, and Ongsa plays Prince Thinnakon, a young man of royal lineage. Their characters grow up together, are separated by rank and family, and are brought back together as adults while Siam moves through the political upheaval of 1932.
The pairing began with a lead billing rather than a supporting arc, which is unusual: most Thai screen pairings are introduced in a side storyline first and promoted only if the response is strong.
A pairing introduced straight into lead billing on a period production rather than tested in a supporting arc first. The dynamic the series is built on is distance: rank, household and tradition keep pulling the two characters apart, so the rapport has to carry across separation rather than proximity. One31 positioned The Edge of Horizon as a flagship 2026 release on the strength of that first pairing.
First time together: The Edge of Horizon (2026) is the first production in which Inn and Ongsa act opposite each other.
Introduced by the network: the pairing was announced by One31 itself on 18 June 2026, two days before the premiere.
Different starting points: Ongsa has been working since 2020, first as a contestant on The Voice Kids Thailand; Inn made his acting debut only in 2025 with The Wicked Game.
Eight years apart: Inn was born in 1997 and Ongsa in 2005.
Period debut: unusually for a new Thai screen pairing, their first series together is a historical drama set in 1932 Siam rather than a contemporary campus or workplace romance.
