In this work, Koo Ja-sung plays Hyeon Seung-hoon, who tries harder than anyone else to earn a living for his family, but dreams of such splendid success, and plans to transform himself into an ambitious man who makes difficult choices in love and dedication for his family after quitting football due to an injury. In particular, as Koo Ja-sung was greatly loved as a sweet sunshine younger man in his previous drama "Was It Love" last year, attention is being paid to him, who has not only changed his conflicting image through "Desire" but also challenged himself to act as a strong character that he has never seen before.
