A close friendship between two idols of the same sex. Both male and female idols have couples, but some groups don’t have couples, and some couples can span groups. Couples often have names that are combinations of two idols’ names. For example, SHINee’s Jonghyun and Key’s couple name is JongKey.  Some fans may read romance into these relationships.
