Since Hwa Rok doesn't have any experience writing crime mystery novels, I have a hunch she'll need Soon Deok's brother Lieutenant Jung's expertise to give her writing input and advice 😉😉😉
Ahhh, really? That adds a different depth to scene then. I might rewatch. I thought she meant her actual biological…
At first, I thought so too, but the way Soon Deok kept mentioning her 'brother' to the point that Jung Woo was a bit jealous got me thinking what she actually meant was her late husband. The romantic lantern festival and the atmosphere of visitors looking to matchmake themselves or their children definitely brought her memories back to her beloved husband and their sweet marriage. I could even guess that her wish when she released the lantern had anything to do with her husband, you could tell how she was lost in thoughts watching the soaring lantern.
Some people guessed that her friend is the one FL's mother-in-law killed (but not dead).
