Things have started to take a U-turn in Absolute Value of Romance episodes 9-10. While Eui-ju was not a fan of Woo-su because of the pressure he was putting her under, after the last episode, where he gave her the pass to write her novels however she wants to write them, Eui-ju has started seeing Woo-su from a different perspective.

She tries getting further information on who Deul-i is and what her history is. However, Woo-su, after seeing her change in behavior, tells Eui-ju that if she doesn’t score above fifty in math, he will tell her parents about her novel.
