The age of Song Joong-ki and Song Hye-kyo’s characters in the drama were revealed Wednesday.

Despite much speculation that Song Joong-ki’s character is older than Song Hye-kyo’s, the two are both 32 years old, born in the year of 1983.

On the latest episode that went on air on Wednesday, Yoo Si-jin, played by Song Joong-ki, encounters Han Suk-won, the head of the hospital where his girlfriend Kang Mo-yeon, played by Song Hye-kyo, works. Han, who has a crush on Kang, was curious about who her boyfriend is. And when the two men finally run into each other inside the hospital’s elevator, Yoo introduces himself.

“I am Yoo Si-jin, born in 1983, Pisces horoscope, blood type A,” he told Han.

Earlier, Kang’s age was revealed when Yoo saw Kang’s paperwork for her medical voluntary service abroad. Kang was born on Sept. 14, 1983.

In past episodes, the two have been using polite, honorific languages to each other, making viewers curious what their real on-screen ages are.

“Descendants of the Sun” airs every Wednesday and Thursday at 10 p.m. on KBS2 channel.
