SHINee's Minho has shared a farewell message in a series of Instagram posts before his enlistment.

As reported, the idol had applied to join the Republic of Korea Marine Corps back in January. When the application was approved, SM Entertainment made an announcement on April 13 that Minho will officially enlist later today on April 15 KST. 

In his last letter to his fans, Minho wrote: "time has flown by so quickly since the debut on May 25 in 2008. They were all happy, joyful, and unforgettable moments, because we shared such wonderful memories together", "I will consider this as a period to reflect upon myself and the past", "I will miss you all so much. I feel so bad for having been unable to approach you guys easily to express my feelings!", "I will never let you down."

Along with the handwritten letter, Minho uploaded a video of himself getting his head shaved.
