Lilly Sarinya Olsson

Lilly Sarinya Olsson (Thai: ลิลลี่ สรินยา ออลสัน) is a Thai actor, production manager and stage manager. She plays Karn in the 2026 revenge thriller Payback, appearing across all ten episodes; the casting was announced on the production’s own X account, which billed her as “LILLY SARINYA OLSSON as KARN” alongside Francis Tanarit Photkanawat as Kavin.

She is the most formally qualified member of the Payback cast. Her published biography records a Bachelor of Communication Arts in performing arts from Bangkok University, followed by a master’s degree in management taken jointly through the Maastricht School of Management in the Netherlands and Chulalongkorn University, an academic route through European business education that has no parallel elsewhere in this ensemble.

That training shows in how she describes her work. She is a freelance performer rather than an agency artist, and her professional identity spans both sides of the camera: production manager and stage manager as well as actor. It is an unusual combination in the Thai BL industry, where performers are more typically signed to a studio that also produces their vehicles.

Her documented screen career begins in 2023 with a guest appearance in 7 Days Before Valentine. The following year brought two supporting roles: Nan, an online gambler, across eight episodes of 4MINUTES, and Toon in Never Enough. 4MINUTES matters for what came next: it was written by Sammon and produced by Rungrapee Kingkaew, both of whom went on to make Payback, so she arrives on this production having already worked with its writer and its producer.

2026 has been her busiest year by a wide margin: Necromancer across ten episodes, The Evil Lawyer as a gynecologist, the film THE (UN)FADED as The Carer, the announced An Affair of Life, and Payback. She posts on Instagram as lillyolsson. Her registered name carries the middle name Inger alongside the surname Olsson; no source describes her family background, so BLGLFLIX makes no claim about it. No birth date, height or weight has been published for her either, and those fields are left blank.
