BIOGRAPHY
Tui Chayatorn Trairattanapradit (Thai: ตุ้ย ชยธร ไตรรัตนประดิษฐ์; born March 24, 2004) is a Thai singer, songwriter, and actor, a member of the boy group LYKN signed to Riser Music, and an actor signed to GMMTV. He plays Thirawat “Beer” Chaemthai in A Dog and a Plane (2026), the GMMTV boys’ love series led by Tay Tawan Vihokratana and New Thitipoom Techaapaikhun.
He is an only child who began singing at age six or seven and took up dance around age fifteen. He studies at Srinakharinwirot University’s College of Social Communication Innovation, majoring in acting and film directing. He is a multi-instrumentalist, playing drums, piano and guitar, and is also known as a skilled beatboxer.
He placed third on GMMTV’s survival show Project Alpha in October 2022, which led to his formation into LYKN alongside four other members. Within the group he contributes as a songwriter and producer; he wrote and composed the fan-song “LYKYOU” performed at LYKN’s first concert, and released his first solo original soundtrack, “From Now On,” in August 2024 for the series Kidnap. He made his acting debut the same year in ThamePo: Heart That Skips a Beat (2024 to 2025) as Pavee “Pepper/Per” Warisphol, a member of the series’ fictional boy band MARS, before joining the cast of A Dog and a Plane (2026).
BLGLFlix editorial view
He writes the songs as well as performing them.
Tui Chayatorn Trairattanapradit, born 24 March 2004, appears as Thirawat in A Dog and a Plane. He is a member of LYKN under Riser Music and signed to GMMTV for acting.
Inside the group he is credited as a songwriter and producer rather than only a vocalist, wrote and composed the fan song performed at their first concert, and released his first solo soundtrack in August 2024 for a series he was not in. Most performers catalogued here stand at the other end of that arrangement, with the music around a career written for them by somebody else.
He plays drums, piano and guitar, beatboxes, and is studying acting and film directing at university, so the writing is not incidental to the career, it is most of it.
One detail on his page needs stating plainly. His stage name is Tui. The name Beer belongs to the character he plays and has appeared in some listings as though it were his, which is the kind of small error that spreads once one database repeats it.
His birth date, agency, label, education, a dated 2022 start and four verified references are recorded. His birthplace is entered only as Thailand, since nothing published narrows it.
