The caption read, "'Infinity Challenge' youngest member Kwanghee! You've worked so hard during the past two years. �We look forward to your safe return after completing your service in the army."

Per his wishes, his enlistment was indeed a quiet one with only Kwanghee being present. His family nor the 'Infinity Challenge' members were anywhere to be seen. It was reported that the members were not able to attend due to their conflicting schedules. He spoke to the press, "I will return safely. I plea that you would all stay healthy and don't forget me."

When one of the reporters asked, "Aren't you sad that the 'Infinity Challenge' members didn't come to see you?" �Kwanghee then replied, "It's okay. I spoke with them over the phone."

After he completes his five-week basic military training, Kwanghee will be serving in the military band.
