Part 4/7:
As the story progresses, themes of love, technology, and fate intertwine through the Love Alarm app—an app that predicts love based on mutual feelings. JoJo's reluctance to disable her 'Shield' feature on the app has led to a disconnect between her and Yun Jong, who genuinely cares for her. The app's anticipated upgrade brings new potential complications, as it could reveal true feelings that JoJo has hidden not only from others but also from herself.
