It may still seem surreal to many fans but�Se7en will be enlisting in just a few days!

Many celebrities previously showed their support for the singer, and 2PM's Jun.K made sure to give his farewell greeting as well.

Jun.K tweeted on the 16th, "Farewell Se7en Dongwook hyung!! I prepared flowers for you hyung keke. I love you brother. Please stay healthy hyung", and shared a snapshot of him and Se7en showing their brotherly love for each other. Jun.K also prepared flowers to show his support for Se7en's enlistment.

Se7en will leave for the Uijeongbu 306 Reserve Battalion on March 19 to officially start his post as an active-duty soldier.
