On June 27th, the Wonder Girls congratulated Sohee on her birthday through Twitter messages. First to tweet was Yubin, who said,

"Happy Birthday Sohee. Let's burn it up later"

Lim also mentioned Sohee, saying,

"Sohee, Happy Birthday"

In the afternoon, Yeeun posted,

"Our Sohee is 20 years old. I can't believe it."

Fans who saw the tweets commented, "Though it is short, they show each member's character", "Looks like Yeeun can't believe that Sohee is an adult now", and "Yubin seems like a wild unni". Several netizens are waiting for leader Sunye's final congratulatory message. Some have said, "Can't believe the leader Sunye hasn't posted a message yet. I wonder if she is waiting to give her message last" and "She probably already congratulated Sohee in person but I wish she would post a message too." Source: Newsen via Nate
