Joo Da's smirk + her ignoring the clock hand going backwards is making me think she's self aware.It's probably setting us up for Lee Do Hwa helping her break out of the stage. She had a lot of screen time lately with how the mom is getting involved. Pics, money for the treatment... (all the mother's plan) If Baek noticed Eun Dan Oh acting out of character from the book, and now Baek is self aware. Then those bench talks with Lee Do Hwa and Yeo Joo Da will have the same outcome.
