Song Joong Ki recently starred in a secret project, planned by the organization Coupang, to help a young girl with a tough life. The project was revealed via a moving video posted on the 26th. The girl's father passed away at an early age, and her elder brother works away from home. Thus, the young girl must take care of her alcoholic mother and younger siblings, including a younger brother who suffers from a mental illness. As the video follows their lives, it is also revealed that on top of all of that, the family's home was burned to the ground in a fire.

The team worked together to build a home for the family and fill it with household items and clothing. The project took 45 days, 135 volunteers, and more than 1,200 sponsors to make possible.

Song Joong Ki enlisted in the army on August 27.
