BTOB's Changsub, who enlisted as an active duty soldier back on January 14, seems to be adjusting to life in the military well!

Fans have recently discovered photos of Changsub with his fellow soldiers in training at the basic training center, which you can check out below. Media outlets have also reported that Changsub was actively participating in his basic training, becoming his dormitory's representative and placing 1st in combat practice sessions. 

But one glaring detail that many Melodies noticed is that Changsub's "military photos" look just like his high school graduation photos!

Some commented, "His head is so round keke. Just like when he was in high school kekekeke", "Wow, this oppa got years younger after going to the military? He went back to high school?", "He's... seriously 100% the same as his high school photo??", "Same old Lee Changsub kekekeke", "He looks like he enlisted right after high school like a normal person kekekeke", "The definition of round kekekeke", and more. 

Nonetheless, it's great to see Changsub healthy and well in the military!
