Baekhyun is the sixth member of EXO to enlist in the military following Xiumin, D.O., Suho, Chen, and Chanyeol. The youngest members of the K-Pop boy group, Kai and Sehun, are set to enlist soon as they will be reaching 30 years old in Korean age. Lay is the only EXO member not expected to enlist as he is of Chinese descent.

Meanwhile, leader Suho previously teased on his Instagram account that EXO will be making a comeback as a full group this year. Fans are gearing up for this comeback as all nine members of the K-Pop boy group are now once again active in the industry.

Baekhyun debuted as part of EXO back in 2012 with the song, "MAMA." The group is composed of nine members, of which seven have already made their debut as solo artists.
