- Choi Kil-soo was set to marry in three weeks
- "I had to carry out my mission," Choi Kil-soo said
Firefighter Choi Kil-soo waited until everyone was out of the third-floor apartment before jumping out of the burning building himself.
But he broke his hip in the fall -- meaning he won't be able to walk down the aisle for his wedding, which was scheduled to take place in three weeks.
Video from the scene shows Choi Kil-soo shielding the residents from the flames as they climbed out the window.
"All I could think of was rescuing the residents. I was holding onto a handrail, but my gloves were already on fire," he told KBS.
With all the residents out of harm's way, the brave firefighter crashed to the ground, fracturing a hipbone.
The firefighter had to postpone his wedding, but speaking to KBS from his hospital bed, he says he did what he had to do.
"My mission is to save people. I acted out of instinct rather than out of knowledge, because I had to carry out my mission," Choi Kil-soo said.
