i think sangwoo and bum is not siblings. if they did ,bum should gave some sort of reaction when he saw the lady when they skiing. only sangwoo did have reaction.
Bum was very young when his parents dead and he doesn't remember how she looked like. When Sangwoo asked if Bum looks like him mom or dad, he wasn't sure, but said "They say I look like my mom".
