Park Ja-seong was a successful businessman and CEO of Park Industries. He had a cold and standoffish approach to life, which often came across as rude and insensitive. He was known to be aloof and unapproachable, often speaking few words and mostly ignoring those who tried to talk to him. Despite his wealth and influence, he was a distant and unemotional individual, who did not seem to care much for the feelings or opinions of others.
