Saeyeon is a North Korean Defector
it's a cool character detail. back in chapter 52 woonhyung joked with saeyeon asking if she left her brain behind after "defecting", and chapter 84 confirms that her father had her run across the north-south korean border for freedom. he said he would follow behind her but he likely got captured or killed by north korean forces. then down the line this is how wang dokpil was able to recruit saeyeon to his training ground.
