In an exclusive, media outlet OSEN talked to an acquaintance who is said to be close to both Song Joong Ki and Song Hye Kyo. The mutual acquaintance stated, "The truth is their love started before the airing of 'Descendants of the Sun'. The filming began in 2015, so their love started then. ('Descendants of the Sun' began airing in 2016)."

The person continued, "In the beginning of last year, Song Joong Ki secretly sent snacks to Song Hye Kyo while she was participating in a photo shoot. This was before 'Descendants of the Sun' aired and the staff members were confused as to why Song Joong Ki was there."

A source who is close to both Song Joong Ki and Song Hye Kyo said that they both would go together on overseas schedule. Even though the schedule would only be for short periods like 1 or 2 days, they would still accompany each other. Before dating with Song Joong Ki, Song Hye Kyo was revealed to have felt uncomfortable with the idea of dating a celebrity. Despite those feelings, Song Joong Ki put effort into the courtship and she eventually opened up.

They didn't really make an effort to hide their relationship to acquaintances. When a person who they both trusted would ask about it, they would respond indifferently. 

The source added, "They really didn't want the news of their relationship to be revealed by the media. That is why Song Hye Kyo and Song Joong Ki revealed their relationship through the press directly through their words, as they believe that is a courtesy for the fans."

It was also revealed that the two families of Song Hye Kyo and Song Joong Ki have already met. They're also taking care of each other's staff members.

Song Joong Ki and Song Hye Kyo will be getting married on October 31 (Halloween Day).
