The story revolves around Sugihara who was born in Japan to a Korean family. His father, former boxing champion, taught him boxing ever since he was a kid and it became useful when he transferred to a Japanese high school and was often getting ganged up by other students. In that school he falls in love with a girl and starts dating her. Sugihara hasn't told her yet that he has Korean blood running inside him because it might ruin their relationship, as Koreans are being harassed in their society. How will their love turn out and will he ever be considered as 'human' in society?
Both films discuss the issue of Korean people living in Japan, their families and so on. They show the difficulties those people have to face and the conflict they have with themselves being both Japanese and Korean at the same time.
