On July 5, Song Hye Kyo wrote on her official fan cafe, "Song Joong Ki was a colleague I worked well with at first. After working on a drama project together, I felt our values and thoughts were similar, and we communicated well no matter what we talked about."

She added, "As he was a good colleague and friends, we contacted each other after our project was finished, and that's how we got to know each other. The trust he made me feel after a long time and the trust in the future I had with him made me realize his sincere feelings towards me. That's when I became sure."

Song Joong Ki also posted to his fan cafe:

"I met a drama project that made me shine and was an honor to me, and I made a precious friend who spent that happy time with me. We confirmed our sincere feelings for each other and became a couple who loved each other. At the beginning of 2017, we made a promise to each other to spend the rest of our lives together. We'll fill what we each lack with love, and we'll live a new life where we can face difficulties together. I plan to marry Song Hye Kyo at the end of October 2017. I wanted to let you all know of my sincere intentions earlier, but it's not something I can decide on my own. My family's opinions are also all precious, and it was a situation where I had to think carefully and discretely. I had an upcoming movie that involved many people's passion and efforts, and as an actor, I didn't want my personal life to negatively affect the film crew and staff. In the future, I'll live as a cool actor and stable head of a family. Please cheer on our good destiny. Thank you."

Congrats to Song Joong Ki and Song Hye Kyo once again!
