M4M has released "Sadness" MV! 

Apparently Cube Entertainment collaborated with Chinese company Xing Tian in the formation of M4M.

I guess that's why their debut song is in Chinese?

Though it might be a tad strange for them to have a Chinese debut song in Korea, no?

I'm not saying it's bad since I actually quite like this song :) Really, I'm hoping that the group will be well received.

How do you guys find it?
