Can't she give her man a flirty smile once in a while? A tender touch maybe?

Afraid not.... she was a successful business woman in her previous life and never had a relationship before, so she doesnt view having a relationship would be "useful" to her
she does slowly fall for him but it will take a long time for her to to fully accept him
Dont forget she is 14-15 years old, even though her soul is very mature lol

She has a bit of the old lady "Devil Wears Prada" vibe

lol she is tsundere

I could do without that cat meowing all the effing time, so annoying it takes away from the show for me
