Actor Kang Hyung-seok, 34, drew public attention on October 29 by sharing an all-black mirror selfie on Instagram that showcased a sharp, structured aesthetic. Dressed in a tailored black jacket, matching shirt, and trousers, the versatile performer paired his minimalist wardrobe with a composed expression while holding his phone to the camera.
From Supporting Roles to Multigenre Lead
TopStarNews reported that Kang’s recent mirror selfie highlights a robust career trajectory spanning theater, television, film, and short-form content. Since his 2019 television debut in the tvN series Crash Landing on You, he has systematically expanded his filmography through a mix of supporting and leading turns.
Early career milestones included playing Ahn Jung-ho in the KBS 2TV series Do Do Sol Sol La La Sol, which marked his first substantive supporting part. He later cemented his presence as the warm-hearted police officer Choi Eun-chul in tvN’s Hometown Cha-Cha-Cha and contributed to the emotional foundation of JTBC’s Disqualified as Jun-hyeok.
In 2022, he demonstrated his range by navigating domestic realism and romance as Woo Kwang-nam in tvN’s Love in Contract. His cinematic footprint expanded concurrently, featuring a comedic yet sincere lead turn in the 2021 film Let’s Get Together as Kim Eui-sung, followed by a pivotal role in the Korea-Singapore joint venture Auntie in 2022 and a supporting appearance in the 2024 film Officer Black Belt as Kang Joo-seok.
Current Small-Screen and Short-Form Projects
Kang has continued broadening his output across broadcast channels and OTT platforms. In 2025, he took on the lead role of Bong Seon-wook in tvN’s Please Don’t Drink, portraying intricate interpersonal dynamics and emotional nuances. That same year, he joined the Disney+ original series The Murky Stream as Choi Dae-il.
Currently, Kang appears in the Disney+ and Channel A series Dive to You. In the time-travel narrative centering on brothers Yoon Ha-na and Yoon Ha-ru, he portrays film director Yang Jun-mo and Chu Si-han, a character tied to a mysterious camcorder. His performance balances a protective, warm leadership style with an underlying sense of tension.
Simultaneously, Kang made a distinct impression in director Lee Joon-ik’s vertical short-form drama Father’s Home Cooked Meal. Playing a youthful Go Ha-eung, he depicted a young man migrating from Gyeongsang Province to Seoul, working as a shoe repairman, and growing into a responsible family provider. The project debuted via Lezhin Snack and secured film festival invitations.
