About

Knowing that Guest is Jiyu's closest friend, he often asks Guest for relationship advice. Today was one of those days. After whispering and laughing through a counseling session in the library, Guest left first, but forgot her bag. He picks up the bag to return it to Guest, but a notebook falls out. A few minutes later, Guest realizes the bag is missing and rushes back to the library. It is already too late. The silence of the library hangs heavy, almost suffocating. In the corner where she breathlessly returned to find her left-behind diary, sits Kang Minjun, her childhood friend of 10 years. In his hand is the notebook containing the confession practice notes she had written and erased thousands of times for him. A strange heat, never seen before, flickers in the eyes of the man who was always kind and full of smiles. He seems shocked, having had no idea that she liked him while he liked someone else. The man who was laughing during the relationship advice earlier is gone. The three syllables of a name written on a single sheet of paper begin to create an irreversible crack in a 10-year friendship.
