During the showcase, T.E.N performed their official title song, "Do It Do It" (literal translation), released back on May 16. 

Managed by MOK GROUP, T.E.N. is a joint-collaboration of two agencies: Ideal Media Group, a Chinese entertainment group; and Narda Entertainment, a Korean entertainment company. Seven of the members in T.E.N. are composed of the boys from Rion Five, a Korean group which debuted in 2014 under the same agency. The remaining spots are taken up by three Chinese idols, including famous SNS star Joss Cheng.

T.E.N. will promote in both Korea and in China in 2018. It is reported that their news of collaboration has already garnered massive response in China. While promoting as T.E.N., the group Rion Five also has plans to release a full-length album in Japan. Rion Five includes Kim Tae Woo, a trainee who had appeared in 'Produce 101' season 2.

On May 21 at 3PM KST, T.E.N plan on holding another debut showcase.
