Playing Kang Tae-mu, a brilliant, perfectly groomed, and ultra-wealthy third-generation corporate CEO who accidentally ends up on a blind date with one of his own employees (played by Kim Sejeong), his performance was an instant viral hit. The show’s fast-paced, laugh-out-loud webtoon energy completely dominated Netflix’s global charts, making it the absolute number-one recommended entry point for any new fan.

2. Dr. Romantic Seasons 2 & 3 (2020–2023) — The Blueprint of Creative Growth

If you’ve only watched him play a glamorous billionaire, you haven’t seen the true depth of his acting talent.

His nuanced portrayal of a cynical outcast growing into a deeply compassionate medical leader earned him massive critical praise.

4. A Time Called You (2023) — A Complex, Multi-Generational Challenge

This gripping Netflix original series served as a bold professional leap for the actor. Based on the legendary Taiwanese mega-hit drama Someday or One Day, the intricate mystery-romance requires Ahn Hyo-seop to pull double duty, executing complex multi-layered roles across entirely different eras and age groups.
