It has been announced that Yoondong, a former member of K-Pop boy group HALO, will be debuting in a Japanese boy group named 'Orbit Union'.

Yoondong was recently announced as one of the members of Orbit Union alongside his fellow 'Produce 101 Japan' trainees, Miyajima Yugo and Osawa Shunya.

Back during 'Produce 101 Japan', Yoondong garnered immense popularity from Japanese viewers alongside his fellow former-HALO members Younghoon and Heecheon; however, the three trainees decided to drop out of the program toward the end of the show. 

Now, it looks like Yoondong will keep going, and will be debuting in Orbit Union, making him the sole Korean member as of now. Orbit Union is expected to add more members to the group's lineup soon.
