There, she connects with a user known as Jemulpo Gangju, finding solace in their conversations as a fleeting escape from her painful reality. This digital refuge offers her a brief respite from her unrequited love, allowing her to share her feelings with someone who feels safely distant from her everyday life. However, her sense of security is upended when she returns to school after winter break and unexpectedly encounters the very person she believed existed only behind a screen. Standing before her is Jemulpo Gangju, revealing that the anonymous confidant she trusted is actually present in her real world. The shock of this reunion transforms her private sanctuary into a complicated new dynamic as he recognizes her immediately, greeting her with the nickname Dolmengi. What began as a harmless digital escape now collides with her daily life, forcing Ji-Eum to navigate the blurred boundaries between her online vulnerability and an unforeseen real-world connection.
