His mother also expressed her pride and gratitude for his role, sharing memories from the VIP premiere of Colony.
“This all reminded me of the day we were so happy after hearing that he had been cast as ‘young Seo Young Chul.’ To think he would be playing the child version of the amazing actor Koo Kyo Hwan. And just being able to take part in a work by director Yeon Sang Ho was such a grateful and honorable experience.”
