In the 1990s, Han Mi-mo, Baek Da-jung, Go Dong-mi, Hong Ae-ran and Goo Seul-ah were members of the successful idol group “Angels", but the group disbanded in 2003 due to Seul-ah's intolerable attitude and meanness as she was the most popular member of this group. Back to present, Mi-mo and Da-jung now work as reps for a remarriage consulting business, Dong-mi becomes a elementary school teacher while Ae-ran is a representative for an internet shopping mall. All of them have their own problem with their marriage or their affection lives, and they are still friends except with Seul-ah.
