Son Bo-seung, the son of comedian Lee Kyung-sil, is earning attention for his striking performance in the Netflix series “Trigger,” where he portrays a school shooting suspect in a society unraveling under the weight of illegal firearms.
“Trigger,” a dystopian gun-disaster action thriller starring Kim Nam-gil and Kim Young-kwang, unfolds in a Korea plagued by the mysterious spread of untraceable firearms and a surge in gun-related violence. The series follows two men who take up arms for different reasons amid mounting chaos.
In the series, Son plays Seo Young-dong, a victim of school bullying who descends into darkness and unleashes a shooting spree.
Starting off as a quiet, innocent figure, Son transitions with chilling precision into a hardened, emotionally scarred youth holding a gun. His performance leaves a lasting impression on viewers from episodes 2 through 7.
His mother, Lee Kyung-sil, acknowledged her son’s performance on social media, writing, “That’s Bo-seung in ‘Trigger’ on Netflix. He appears from episodes 2 to 7. He’s doing pretty well.”
Online audiences echoed her sentiment, with comments like, “I wasn’t sure at first, but it was definitely Bo-seung,” and “He acted really well.”
A graduate of Anyang Arts High School, Son made his debut in the 2017 drama “Father, I’ll Take Care of You,” and has since built his filmography with various projects.

Son gained wider recognition through his role as the butcher’s son in the 2023 Disney+ series “Moving.”
In his early twenties, Son became a father, with a son born in 2022. He recently appeared with his mother on TV Chosun’s reality show “Lovers of Joseon,” and is currently serving in the military.
