I'd be quite surprise if "Secret" sale a million copies! It would be amazing. I'm pretty sure it will beat "(m)u". Though, the "Secret" single tracks aren't great. The "(m)u" single tracks were amazing! But it's the opposite for the album tracks. (Even though I haven't heard the previews, I'm pretty sure it's better hehe.) Plus, "Secret" has more album tracks! Hopefully, it will sale better!
