A small Korean man of unassuming character, Gun prefers the company of computers to people, and does not try to keep it a secret.

After getting to know him (a difficult feat!) you may even find out that he has had the pleasure centre of his brain removed to cope with the extreme anxiety being around people caused, which was resulting in severe depression. The operation was a success, and now he just prefers to avoid people, or rather, communicating face to face with people more than he has to.
