Both the single and its music video were released on February 13th.
The phyiscal version of So Wonderful, while very rare, is more common than LADIES' CODE's other digital single, Hate You, because it was performed on both music and radio shows. The Promo CD was also given away by Soompi on Lee.Bahl.Show's radio broadcast.
A So Wonderful slogan was also available on the LADIES' CODE Daum Cafe for a limited time in March 2014.
