Former After School leader Kahi promised “Mighty Mouth’s” Sangchu that she will visit him in the army.

In the morning of October 30, Kahi posted a photo on Twitter along with a message, “Goodbye Sangchu! You’ll do great in the army. Good luck!! I will bring kimbap and visit you. Take care, haha.”

In the picture is Kahi with Sangchu who has shaved his head. It is a well-known fact that Kahi and Sangchu are close friends.

Netizens who saw this picture replied, “They must really be close,” “If Kahi promises to visit him in the army, Sangchu will be popular there,” “So Sangchu has been enlisted, just like Leeteuk,” “We will be waiting for your comeback in two years,” “If Kahi really visits the army, the soldiers are going to go crazy,” “Military cut looks good on you,” “Long time no see, Kahi.”

Sangchu has entered the military ground on October 30. After five weeks of basic military training, he will be accepted officially.
