Episode 16 begins immediately after Eui-ju confesses her feelings to Woo-su. She’s nervous about what will happen next, but when he asks her to meet him at a cafe on Saturday, she can feel her excitement rising.
Eui-ju makes a careful effort to dress up for the occasion, thinking she might finally get an answer to her confession. But her hopes are crushed when Ha-su turns up for an important meeting.
It gets even more awkward when the girls realize Woo-su invited the whole Math Club instead of setting up a private time to talk with her.

Word of his condition soon reaches Eui-ju at school. She leaves the campus, concerned about him, and goes to see him after the operation.
With his eyes wrapped in bandages, Woo-su shares a memory that has haunted him for years. He says he met Eui-ju when she was a little girl, during a previous hospital stay. Woo-su says that while he was recovering from surgery he helped her with math, and it left a lasting impression on him.
For Eui-ju, the revelation seems to matter. Learning that she played a part in his memories gives her hope that their connection may be more than she thought.A Childhood Memory Raises New Questions
Eui-ju tells her parents the story excitedly back in her home town. Surprisingly, they claim they never took her to the hospital Woo-su described.
Eui-ju is confused and unsure about their denial. She starts to wonder if Woo-su made up the story, or if he just got the facts wrong.
Meanwhile, Woo-su takes a big step in his personal life: he conquers his fear of being on camera. He talks about his choice to become a teacher in a documentary interview, again referencing the same meeting with the young student in his childhood that made him want to become an educator.

Eui-ju finishes her popular BL web novel after school at last.
The story ends with a funny romantic confession that creates an odd love-triangle. Rather than have a typical wrap-up, the characters choose to remain together, and accept an unusual situation.
The novel becomes a hit, becoming the most successful web novel of 2026. This accomplishment signifies Eui-ju’s creative maturation and one of the drama’s most satisfying personal victories.# Ending Explained: What Happens to Eui-ju and Woo-su?
Later in the episode, Eui-ju’s parents acknowledge that they were wrong. They recall old memories and realise they had actually visited the hospital years ago while Eui-ju’s father was receiving treatment.
This confirmed Woo-su’s story was true all along.
Before leaving for a long trip to the United States, Woo-su and Eui-ju say a quiet goodbye to each other. She leaves him a first-aid kit as a parting gift and talks about her future projects in writing.
Notably, Woo-su never answers her romantic confession directly. Their farewell is instead one of mutual respect, friendship and support.
The series ends with the season’s first snowfall. Eui-ju takes a moment to enjoy the outdoors while Woo-su watches her from a distance, leaving their future relationship up in the air.# Final thoughts
The finale is to be credited for not fully realizing the teacher-student dynamic as a romance. By not allowing Woo-su to overtly reciprocate Eui-ju’s confession, the drama avoids a much more problematic ending.
But the episode undercuts that decision by the way it handles the childhood connection story. The last-minute addition of a “destined meeting” story adds unnecessary ambiguity and encourages viewers to keep rooting for a relationship that the series never fully supports.
The finale also has the annoying element of Woo-su not being able to properly respond to Eui-ju’s feelings. The story doesn’t answer either, instead it leans on vague emotional moments and lingering glances that leave too much to interpretation.
This issue is further highlighted in the farewell scene before his trip to America. The series doesn’t quite push them into a couple, but it teases the possibility, and the ending seems conflicted about what it wants to say.
And so ends Absolute Value of Romance, with a bittersweet feeling. The strongest parts of the finale are the aspects of friendship, personal growth, and Eui-ju’s development as a student and writer. Unfortunately, the unresolved romantic tension makes the episode end on a not entirely satisfying note.## Rating: 2.5/5
A finale with some nice emotional moments, but one that doesn’t quite commit to its most important relationship decisions.
