SM Entertainment has confirmed on July 8, Wednesday, that Onew will be taking his final leave today and will be discharged without returning to the base. There will be no separate discharge event.

The agency said that Onew will be discharged twelve days early following military orders. Due to the ongoing COVID-19 pandemic, all men enlisted in the military will be discharged earlier to prevent the spread of the virus. The timing of how early depends on how many days of vacation they have left from their final vacation from the military.

Onew had enlisted in the military on December 10, 2018. In July 2019, he joined the military musical, titled "Shingeung Military Academy," which is a musical that talks about young patriots who joined the army to gain independence from Japan.

He was part of another military musical in August 2019, acting alongside EXO's Xiumin. The musical was "Return: The Promise of That Day," in which he played young Seung-Ho, who fought during the Korean war. It's an original army music that discuss topics of digging out the remains of soldiers who sacrificed themselves for their country during the war.

Onew is the first SHINee member to complete his mandatory military enlistment. Congratulations, Onew!
