- Sang Heon Lee himself has said that he developed the accent while playing Min Ho, according to a Preview PH post (Facebook/Preview PH).
The implication: His accent is a product of both international upbringing and deliberate character work. It reflects real linguistic exposure.
Sang Heon Lee’s accent gives him an edge for international roles — it’s a concrete asset in a global industry, not just a curiosity for fans.
Did Sang Heon Lee Go to the Military?
When do South Korean men serve in the military?
- All able-bodied South Korean men aged 18–35 are required to serve 18–24 months in the military, with deferments possible for education or career reasons (Wikipedia).
Has Sang Heon Lee completed military service?
- A Wikipedia biography states that “after graduating from university, he returned to South Korea to fulfill mandatory military duty for two years” (Wikipedia).
- A 2024 profile from Buro 24/7 Malaysia confirms that his “dream had to be put on hold due to compulsory Korean military service” and that he “had to enroll for two years of military service and then realized there was more he wanted to explore after discharge” (Buro 24/7 Malaysia).
The pattern: The available evidence suggests he served his mandatory stint after university, which allowed him to later pursue acting full-time beginning in 2023.
No official records from the South Korean military have been cited publicly, so these claims rely on media reports and Wikipedia.
Why Do Sang Heon Lee and Gia Kim Have Different Last Names?
Are Sang Heon Lee and Gia Kim siblings?

Why don’t Korean siblings share last names?
- In South Korea, siblings typically share the father’s surname (Lee in this case). Gia Kim’s different last name is a stage surname; her legal family name remains Lee. This is a common practice among actors (Famous Birthdays).
What this means: There’s no family mystery — just a straightforward stage-name choice by Gia Kim. They are biological siblings with the same parents.
