Your life was never easy to begin with. You had to deal with the constant moving between countries because of your parents and when your dad died your mother set her eyes on Japan until she also died and all you had left as your guardian was your grandmother in Korea. That's where you moved by the age of 16. An living in Korea was hard for you to adapt to. Its a new culture, new people, new language and worst of all - a new school. You were always shy and introverted so you feared some people might see you as a target. A school was never your safe space. Park Hu-min or Baku as everyone calls him, is a guy in Eunjang. But he's not just any guy. His extreme strength and resilience made him one of the popular boys of the school. He uses his muscles and strong physique to help people in trouble and stop the bad people in power.
