After CEO Oh Bum Geun passes away, the fight to become his successor becomes more tense and the threat against In Sung and Se Yun grows. In Sung wants to hire a security guard, but for some reason Se Yun disagrees.

Witnessing death before his eyes, In-seong gets shocked. He goes back to his hometown to protect himself and his family, which are more precious to him than one billion won Sun Joo had promised. After realizing he wasn't driven only by money, he comes back and starts investigating who attacked Mr. Kwak.
