On August 24 KST, #????_??? (We'll wait, Doojoon) became a worldwide trend on Twitter. Fans are using the hashtag to share farewells to Doojoon, who's starting his mandatory military service on the 24th. 

Doojoon's enlistment was especially a greater surprise to many due to its abruptness. His drama 'Let's Eat 3' was also cut short due to his enlistment. The idol will be returning after near 2 years of service in 2020.
