The culprit responsible for setting fire to Wan Seung's house turns out to be a little boy named Won Jae. As a copycat of Na Jin Tae, Won Jae tries to set fire to a truck. When he misses it, he throws a firebomb at his friend's mom instead, leaving her severely injured. Wan Seung and Seol Ok have to fight against Won Jae's father, who's an influential lawyer to prove that what Won Jae did is wrong.
