  Lee SangWoo (Cast: Park HaeJin)

  Lee SamJae's son and SeoYeong's twin brother.
  
  Unlike his sister SeoYeong, Lee SangWoo has a cheerful and outgoing character. He doesn't blame for his family background or he isn't ashamed of it.
  
  He was a good student, but he never got praised because of his genius sister. But, rather he is proud of SeoYeong and loves her so much.
  
  In a year, SangWoo will graduate from medical school and wants to relieve some of his mother’s burden. However, his mother passes away unexpectedly. His father is a poor guy to him rather than a incompetent father like SeoYeong thinks.
