Confession Disguised as Fiction in Absolute Value of Romance Episode 13
Absolute Value of Romance episode 13 begins with Eui-ju finally attempting to confess her feelings to Woo-su. However, she panics at the last moment. Instead, she tells him she wants to stop attending extra classes.
Woo-su rejects her request. Furthermore, he reminds her that her grades are improving and pushes her to keep the promise she made at the start of the year. Ha-su overhears their exchange and becomes curious about their relationship.
That night, Eui-ju confides in Go-ya. She admits that she still cannot speak directly to Woo-su. Go-ya suggests writing down her feelings instead.
Eui-ju takes that advice and turns to her BL story. She begins rewriting a confession scene between Dong-ju’s character and Woo-su’s character. At first, she struggles. Later, she slowly finds a way to express her emotions through the story, without revealing everything to Go-ya.
The next morning, Eui-ju asks Woo-su to read the new chapter. He criticizes his character for acting out of character. This comment frustrates her. Later, Eui-ju admits she forgot to do her homework. Woo-su immediately scolds her. He reminds her to focus on schoolwork instead of distractions.
Secrets in the Classroom
At lunch, the students talk about Woo-su’s behavior and criticize him. However, Eui-ju quickly defends him. Furthermore, her strong reaction makes her friends suspicious of her feelings.
Meanwhile, Ha-su overhears students discussing the BL web novel We Were Friends. She becomes curious and reads the story. Soon, she realizes that the author is likely a student at their school. Since Eui-ju is the only student she knows who reads web novels and attends extra classes, Ha-su begins to suspect her.
Elsewhere, Eui-ju sees Woo-su smiling while talking on the phone. Jealousy hits her immediately. Moreover, his recent cold attitude toward her leaves her discouraged. Later, she tells Go-ya that she no longer has the courage to confess. She decides to keep her feelings to herself for now.
That night, Da-ju teases Woo-su about Deul-i. The teasing escalates into an argument. Dong-ju and Gi-jeon grow frustrated as they try to stop the fight. Meanwhile, Eui-ju reads the comments on her latest chapter. One comment catches her attention. A reader asks whether the author attends Murim High School, leaving her unsettled.
Ha-su’s Suspicion and Jealousy
Back at school, Ha-su openly brings up the web novel and tries to accuse Eui-ju of writing it. Eui-ju panics and tries to stay calm. Furthermore, she spends the next few days worrying that her secret will be exposed. Go-ya notices her stress and tries to talk to her, but Eui-ju refuses to explain anything.
One day, Ha-su questions Jennie about web novels. However, Jennie refuses to betray her friend and stays silent. Later, after extra class, Ha-su gives Woo-su a drink as a gift. Outside the classroom, Eui-ju speaks privately with Woo-su, which immediately increases Ha-su’s suspicion.
During their conversation, Eui-ju tells Woo-su that she wants to stop writing for now. She explains that she needs to focus on studying instead. Woo-su feels disappointed. Moreover, he urges her not to give up so easily and encourages her to continue writing.
Before leaving, Woo-su gives Eui-ju the drink that Ha-su had given him. Ha-su witnesses the exchange from a distance. The moment triggers her anger and deepens her determination to uncover the truth.
