Fantagio told fans to stop prank calling ASTRO MJ's military base.

MJ enlisted for his mandatory military service on May 9, and he's now serving as part of the military band. However, ever since his enlistment, his military base has been receiving a series of prank calls. Fantagio posted to ASTRO's official fan cafe, "We'd like to thank the fans who support ASTRO's MJ, who started his military service on May 9. More and more people have been trying to make prank calls to MJ's military base recently, and this unnecessary prank calling really interferes with MJ's training."

The label continued, "Additionally, making prank calls several times is subject to punishment, and prank calls to military bases can receive even more severe punishment. So MJ can have a peaceful military service, please refrain from making unnecessary prank calls, and please be aware legal action may be taken if prank calls continue after this announcement."

In other news, ASTRO recently made a comeback with "Candy Sugar Pop". Stay tuned for updates on MJ and ASTRO.
