Do you want to know the answer, strawberryswing?
It's because nobody gives a fuck. Everyone knows the singers in the group are Luna and Krystal. Amber is there so transitioning lesbians and Victoria is in the group for males to fap to. Plus, seeing as how Victoria spends 11 months out of the year filming shit in China, she doesn't need to work on her singing. I'm just hoping she stars in a movie where I can see her tits.
