Thanks for pointing out...yes YCT is a professor-to-be..he is understudying from his own professor on writing novels, maybe.
Of course the PD and scriptwriter are trying to shape Lee Mari, basing on different charcters in their minds...be it Elizabeth or Tess or Emma or others...I like the way CJW acted in a mix of these plus her own acting style from her personality and acting skills.
Wait for coming episodes...
