Shin Ha Kyun will star as Se Ha, a man who has a brilliant mind and an impressive way with words, which he uses to fight back against the prejudices of society. Lee Kwang Soo will star as Dong Goo, a man with outstanding athletic abilities and excellent physical health. The two protagonists each have a different tragic flaw: Se Ha’s weakness is his body, while Dong Goo’s weakness is his brain. Although the two men are not biologically related, they are an inseparable pair of close friends who have spent over 20 years together living almost as a single entity.
