The new idol groups these days have plagued the music industry with the upcoming debuts, however some idols have a similiar situation with each other. These idol members have been known since their trainee days and especially a unique pattern of a famous older sibling singer and a rookie younger sibling.

In SM Entertainment, Krystal of f(x) is the younger sister of the sunbae group Girls' Generations' Jessica. With both sisters in the same company, they have put everything into their singing careers. Recently, f(x) and Girls' Generation had been models for the LG Electronics new Chocolate Phone with both groups promoting the same song with different styles. Jessica had said "Because I am doing a CF with Krystal our parents were very elated."

MBLAQ, with the guidance of Rain, had gained much popularity especially with actress Go Eun-Ah who is the older sister of Mireu and 2NE1's Sandara who is the older sister of Thunder. Also, Mireu's management company also known as Rain's company, J. Tunes' representative is Cho Dong-Won, Mireu's brother in law. In Thunder's case, he was most likely chosen for his loveable and cute charms just like his sister Sandara Park. Rain said "Thunder was picked because the more you look at him the more you get attracted to him."
