The male duo Monday Kiz (먼데이 키즈) was formed by 김민수(Kim Min Soo) and 이진성(Lee Jin Sung). They were signed by "Doremi Entertainment", the same record company as SG Wannabe, Vibe, etc. The origin of their name "Monday Kiz," in an interview they claimed that their first recording in a studio was on a Monday. Thus, "먼데이 키즈" which would usually translate to "Monday Kids," but they decided to drop the 'd' and 's' for a 'z.' They don't want to be known as the "second SG Wannabe" but want their own identity.
