‘EXO’ Kai entered the military training center while being seen off by the members.

On EXO's official Twitter account, a photo was posted with a heart and thumb emoticon on May 11. It was EXO's whole member. 

EXO members gathered together for Kai's enlistment. 

Kai stood in the middle of the members with short hair. EXO made a thumbs up pose for "We Are One".

EXO planned to comeback as a whole group in 5 years. However, not only the fans but also the members were disappointed by Kai's sudden enlistment. 

Kai even showed tears on Instagram Live on May 3. He confessed, "I prepared a lot, but it's a pity".

On May 9, he held a free fan meeting before joining the military. He said, "I really wanted to see you guys before I went (to the military), so I asked you to do it". “We Were preparing for the concert. "I'll come back (after being discharged) and show you guys great performance", he added, "Please wait for what kind of cool appearance I will show up".
