Se Ha has a brilliant mind and an impressive way with words, which he uses to fight back against the prejudices of society and Dong Goo, a man with outstanding athletic abilities and excellent physical health.
They 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 friendswho have spent over 20 years together living almost as a single entity.
