Intro. Shin, a serious and quiet 15-year-old boy, was abandoned by his parents and ran away from the orphanage at 14. He is a hacking prodigy and lives independently. One night, he is kidnapped by some men and taken to a large tech company.
There, he meets Sung, the owner of the company, a cold and authoritarian 22-year-old who is quite attractive and always surrounded by women, though he isn’t interested in any of them. His company is being attacked by a hacker that none of his employees have been able to stop. Sung reveals that they tracked Shin down because of his talent and now demands that he be the one to stop the intruder.
In front of everyone, Sung hands him a computer and challenges him to prove his skills. Shin accepts the challenge, and as he begins hacking, a silent and strange tension arises between the two.
