most likely. or a promo song for his solo album? (i'm assuming he's going to release one!) but i think JE will most likely release a single for this, since as we all know, JE profits off singles.
i don't mind no T&T stuff, but i want Tsubasaaaaa to be releasing stuff too, DAMN IT.
cuz i've always thought T&T their personal debut group project (since they love each other & all that jazz~), but they've always done solo projects outside T&T.
