Descendants of the Sun: Hidden Facts You Didn’t Know

When it comes to iconic K-dramas, Descendants of the Sun (DOTS) easily makes it to the top of the list. Released in 2016, this military-romance drama not only swept across Asia but also created a global Hallyu wave that made millions of people fall in love with Korean dramas.

Starring the charming Song Joong Ki and the elegant Song Hye Kyo, the series told a beautiful love story between a soldier and a doctor, all set against war, disaster, and human struggles. But beyond the romance and action, Descendants of the Sun holds many lesser-known facts that make it even more fascinating. If you’re a true DOTS fan, here are the details you probably didn’t know!

1. The Drama Was Pre-Produced (Rare at That Time)

Unlike most K-dramas, which are filmed episode by episode while airing, Descendants of the Sun was fully pre-produced. This meant the entire series was shot and completed before the first episode even aired. At that time, this was a very unusual practice in the Korean drama industry.

The decision paid off big time—because it allowed for stunning cinematography, high-quality editing, and overseas promotions even before the finale aired.

2. Filming Took Place in Greece

Those breathtaking scenes of Captain Yoo Si Jin (Song Joong Ki) and Dr. Kang Mo Yeon (Song Hye Kyo) against dreamy seaside backdrops? They were filmed in Greece. The show’s producers wanted a location that felt exotic yet romantic, and Greece was the perfect fit.

Fun fact: After the drama aired, many fans started visiting the exact filming spots in Greece, boosting tourism!

3. It Revived Song Joong Ki’s Career After the Military

Song Joong Ki had just completed his mandatory military service when he accepted the role of Captain Yoo Si Jin. There was pressure on whether he could regain his popularity—but Descendants of the Sun not only revived his career but made him an international superstar.

Fans adored his mix of playful charm and heroic bravery, and suddenly, he was on posters, billboards, and fan merchandise everywhere.

4. The On-Screen Romance Became Real Life

Who can forget the incredible chemistry between Song Joong Ki and Song Hye Kyo? Their love story didn’t just stay on screen—it spilled into reality.

The two announced their relationship after the drama and eventually tied the knot in a fairy-tale wedding in 2017. Unfortunately, they divorced in 2019, but for many fans, they will always remain the “Song-Song Couple” who defined an era in K-drama history.

5. The Drama Was a Global Sensation

When we say global, we mean it! Descendants of the Sun aired in 32 countries, including China, Japan, the Philippines, and even parts of the Middle East. It was one of the first Korean dramas to gain massive international licensing deals, setting the stage for future mega-hits like Crash Landing on You and Squid Game.

6. Song Hye Kyo Almost Rejected the Role

Surprising, right? Song Hye Kyo, who played Dr. Kang Mo Yeon, initially hesitated to take the role. She wasn’t sure if she wanted to return to TV dramas at that time. Luckily, she said yes—and her performance as the strong, compassionate doctor remains unforgettable.

7. The OST Was as Famous as the Drama

Who else still hums “Everytime” by Chen and Punch? The Descendants of the Sun original soundtrack (OST) was a massive hit, with multiple songs topping charts across Asia. Songs like “Always” by Yoon Mi-rae and “Once Again” by Mad Clown & Kim Na-young became emotional anthems for fans.

In fact, the OST album sales were so high that it broke records for drama soundtracks in Korea.

8. It Boosted Tourism in Korea

Not only did Greece see a rise in visitors, but South Korea also benefited from the DOTS craze. Fans flocked to Taebaek, where the military camp set was built. The location was turned into a permanent tourist site because of the overwhelming demand.

9. The Drama Won a Presidential Award

That’s right! Descendants of the Sun was such a cultural and economic success that the production team received a Presidential Citation Award from South Korea. Talk about a drama that went beyond entertainment—it became a national pride moment.

10. The Characters Were Inspired by Real Stories

While fictional, Captain Yoo Si Jin’s character was loosely inspired by real Korean soldiers who served in peacekeeping missions abroad. The show’s creators worked with actual military advisors to ensure the portrayal of soldiers felt authentic and respectful.
