A rep from Woollim told media outlets, "Sungyeol is enlisting this March 26. Some time today, he plans on delivering the news personally to his fans with a message. Due to his own wishes, the time and location of Sungyeol's enlistment will be kept private. Only his friends and close acquaintances will accompany him." The idol is expected to enlist as an active duty soldier.
Sungyeol will officially become the second member of INFINITE to begin his mandatory military service, after leader Sunggyu. Dongwoo is also awaiting his enlistment some time this spring.
