BAE173's Yoojun is featured in the latest debut trailer for the group!

In his trailer, Yoojun seems to be in good spirits as he goes for a bike ride on a sunny day. 

As previously reported, "BAE" stands for "Before Anyone Else," "1" stands for perfection, and "73" is a lucky number. BAE173 features Bit, Doha, Youngseo, Muzin, J-Min, Yoojun, and Junseo, as well as former X1 members Nam Dohyon and Lee Hangyul.
