Jakkrasin Atsavatanachai
BIOGRAPHY
Jakkrasin Atsavatanachai (Thai: จักราสินธุ์ อัศวธนะชัย; born 3 November 1997), known by the nickname Inn (อิน), is a Thai actor working with the One31 network.
He graduated from the International Program in Business English Communication at the Faculty of Liberal Arts, Thammasat University, and made his acting debut in 2025 as Phakphum in the One31 action-romance series The Wicked Game.
In 2026 he played Prince Ekathotsarot in the historical drama The Last Duel, then took the lead role of Phopthee Mankhongphak in One31’s historical BL series The Edge of Horizon (อรุณรุ่ง). Phopthee is a commoner, the son of the palace wet nurse Nuan, whose childhood bond with Prince Thinnakon becomes a romance that rank and tradition try to break.
The series paired him with Theethuch Khummuang for the first time, a pairing One31 introduced under the name In-Ongsa.
BLGLFlix editorial view
On screen he is the commoner and his co-lead is the prince. Off it, the positions are the other way round.
Jakkrasin Atsavatanachai plays Phopthee, son of a palace wet nurse, in The Edge of Horizon, opposite Theethuch Khummuang as Prince Thinnakon. In life he is the later starter of the two: a Thammasat degree in business English communication, no screen credit at all until The Wicked Game in 2025 at twenty-seven, while his co-lead was on television at fourteen.
Two historical productions in a single year is unusual for anyone that new. He played Prince Ekathotsarot in The Last Duel before this, so his entire filmography to date is period work, which is a narrow way to start and a demanding one. Costume drama gives an inexperienced actor no contemporary behaviour to fall back on.
One31 introduced the pairing with this series under the name In-Ongsa. Nothing about it is established yet. Two leads, one show, and no evidence either way about whether it lasts.
