Why R U? (2023)

Jung Lee Won is a student at a leading South Korean university. He's majoring in acting and hopes to become a star in the future. His nemesis is Kim Ji Oh, a student in the same academic year who's majoring in directing. They bicker whenever they meet and constantly accuse one another of getting in their way. The nature of their majors, however, means they often have to work together.

Little did Jung Lee Won know, that his younger sister is writing a web novel where he and Kim Ji Oh are lovers! One day, Jung Lee Won uncovers his sister’s secret writings and becomes outraged. He vows that if there is any truth in the fact that he secretly likes Kim Ji Oh, the novel’s fantastic storyline should become reality. He may soon rue this vow, though! At university, he finds he must spend more time with Kim Ji Oh than ever. And he starts to wonder if he really is starting to feel the pull of attraction to his bitterest enemy…
