Two brothers, Jong-hyeon and Seong-hyeon, have been fighting for 17 years. Their rivalry began when their mother favored Seong-hyeon, and escalated when they both fell in love with the same woman, Mi-ryeong. The brothers' long-simmering emotions finally boil over, leading to a massive fight. In the heat of the moment, Seong-hyeon asks Jong-hyeon to call him "hyeong", a term of endearment used by younger brothers to address their older siblings, something Jong-hyeon has never done before.
