T-Max members showed off their friendship despite the official breakup of the group.

On the 30th, T-Max leader Shin Min Chul posted a picture on his twitter along with the comments, "Happy Yoon Hwa Birthday! Fly up Welcome!!! Bro!!! Happy Birthday!!"

In the picture, Shin Min Chul and Park Yoon Hwa are posing happily for the camera. T-Max is a three member group that debuted in 2007. As Kim Jun filmed the drama 'Boys Over Flower', T-Max's soundtrack for the drama became very popular. 

After Park Yoon Hwa left the group for his military service in 2010, Shin Min Chul and Kim Jun added Joo Chan Yang and Park Han Bi to the group, but disbanded in January of 2012. 

Fans have commented, "If Jun comes, its the original T-Max."
