With Song Joong-ki’s extreme popularity, as seen in his new endorsements left and right, and the blockbuster success of the 16-episode “Descendants of the Sun,” fans are asking if it is not only Chinese and South Korean women who are his loyal fans?

The question was raised by readers of Sina after the Chinese media outlet published on Sunday a picture of the 30-year-old actor during his Friday photo shoot in Hong Kong. Sina noticed what appears to be like a female ghost seen on the actor’s right, reported AllKpop.

The photo has Song Joong-ki seated on a low step with a glass window on the background. Some netizens think the smoky figure on the left corner is the image of a girl with long hair. They added the female figure appears to be creepily smiling.

Some readers of Sina said they were scared by the apparent apparition, while others joked that even female ghosts fell in love with the “Descendants of the Sun” actor. But other netizens pointed out it was just a reflection.

Meanwhile, fans of the actor are also talking about another female who was seen in an old photo with Song Joong-ki. But she is not a ghost, rather she is Song Seulgi, his younger sister. Seulgi recently posted a selfie and netizens noticed that she looks beautiful and slim.

It contrasts with an older photo of the brother and sister when both were younger and Seulgi was quite chubby.

Comments on social media include previous comparison that the brother took all the good DNA of the family. Others noticed not only the weight loss of Seulgi but also the improvement in her physical appearance. “She used to be so ugly before she lost weight,” someone wrote. But another netizen pointed out that Seulgi looks a lot like Joong-ki with long hair.
