The series, which aired on MBC, achieved an average nationwide viewership rating of 15% over its 50-episode run. Later that year, he transitioned to the silver screen, taking on a leading role in the short film Butterfly Effect.
His first feature film debut came in 2017 with a supporting role in Excavator, a war film depicting events during the Gwangju Uprising of May 18, 1980.

He also reprised his role in No Bad Days 2, a sequel to the 2017 web series.
From 2019 onwards, Son's career saw an elevation in public recognition and role opportunities, particularly through increased participation in mainstream television series produced by leading South Korean broadcasters like MBC, SBS, and TvN. These productions often achieve high viewership and global interest through the Hallyu phenomenon. He starred in Nokdu Flower, an SBS historical series focusing on the Donghak Peasant Revolution of 1894. In this series, Son portrayed Lee Gyu-tae, a righteous and sympathetic commander of the Joseon Imperial Guard who aids the uprising peasants despite their opposing stances. The series achieved strong ratings, with 13.2% in the Seoul metropolitan area and 11.5% nationwide.
