i’m confused asf. what happened

the guy il-yang woo came to gicheon to kill before he killed himself was baekhee’s father— because baekhee’s father kidnapped and abused him in the past. neither of them recognized the other and neither knew how involved they really were through this. baekhee recognized the scar on il-woo’s arm and finally recognized him as the kid from back then.. baekhee is NOT going to take this well.
