On April 6, FNC Entertainment announced N.Flying member Kim Jaehyun's plans to begin his mandatory military service next month.

The agency stated, "Kim Jaehyun will carry out his basic training by enlisting on May 25, after which he intends on fulfilling the remainder of his duties as a public service worker."

Jaehyun, who debuted as the drummer of N.Flying in 2015, will be the last member of his band to begin his mandatory service duties. Fellow member Cha Hun enlisted in March of this year, while maknae member Seo Dong Sung also recently delivered news of his enlistment on May 8. The band's vocalist Yoo Hwe Seung is known to have completed his mandatory service prior to his debut, while the band's leader Seunghyub received exemption from his mandatory duties as a result of past leg surgeries.
