Girl group EXID sang for their fan's wedding, which became a huge issue.

Recently, EXID posted on their fan website, "Congratulations on your wedding. I hope you have a happy ever after," along with pictures taken at the wedding.

In the revealed pictures, EXID is in neat clothing as guests of a wedding, and are genuinely smiling at the two who are getting married.

When the members of EXID showed up at the wedding, the fan could not hide their shock, and neither did all the other guests at the wedding. EXID members sang a sweet song to match the atmosphere of the wedding.

Internet users commented, "Epic!", "The fan who got married must have been so much happier", "That's so cool", "Their hearts are as pretty as their faces" and "It must be a memorable wedding."
