Even military service cannot break the bond between the cast and crew of tvN's 'Amazing Saturday'!

On May 19, Girl's Day's Hyeri took to her personal Instagram to share images of a recent visit to SHINee member Key's military camp. In the photos, Key is seen wearing his military uniform while posing with not only Hyeri, but Park Na Rae and 'Amazing Saturday' PD Lee Tae Kyung.

"Healthy Kibum Oppa confirmation complete," Hyeri playfully captioned the post.

Meanwhile, Key left the cast of 'Amazing Saturday' back in March when he left to serve his mandatory military service. Both Hyeri and Park Na Rae remain a part of the program.
