Ruby is not Korean, she's Taiwanese (Taiwan), don't ever call her Korean or Chinese, Taiwanese are very sensitive to the Chinese given the political situation between China y Taiwan. To me, they're the same, Taiwan used to be part of China, it's the same family, but you know how it is.
She used to go by the name of Bibi (or Vivi) when she worked at the Golden Spa (former Smile Spa) in Passaic. She's kind of cute, and petite but not that great.
