"I'll do my best!" 

"SF9" Jae-yoon will join the Army's 3rd Infantry Division training center on the 21st. After receiving basic military training, he will be deployed by his own forces. 

There is no separate event. FNC Entertainment announced "minimize congestion at the site." We don't plan to hold an official event," they explained.

Jae-yoon is now the third member of the group to serve in the military. Earlier last year, In-sung and Young-bin joined the military band and the 27th Division respectively. 

Jaeyoon said, "I will adapt well and do well wherever I go." Let's love each other as much as we do now for the rest of the time. "Don't be too sad," he said to his fans.

Meanwhile, SF9 released its 12th EP "The Piece of Nine" in January.
