Comment by PORTOGAS D ASCE on The Princess In The Dumpster - Chapter 51

@PORTOGAS D ASCE in south Korean it's common for also non-related people to call older girls than them noona, some friends call each other that way too sometimes, and some girls who like their idols(like Jimin) that are older than them, they call them Oppa, it's kind of like Nee-san or Nii-san in japanese, though the fact that his brother and his wife have similar hair color is a little concerning, their hair color might be common since the record keeper and his apprentice also have red hair,
