He is the successor to the Sunwoo company and excels in anything to do with the cranial nerve. From his difficulties, he is respected and looked up to as a brilliant man. One day, his kindness destroys his life. Whilst trying to help a woman in trouble, he gets into an accident, and his life completely changes.
