A strange celebration on the anniversary of his brother's death
Outside, a torrential rain pours down, just like the day he lost his brother. Inside the dark study, Yu Jinwoo sits alone with a glass of liquor, facing a cold silence instead of his brother's funeral portrait. Suddenly, the silence is broken as the door swings open. A strange woman, Han Seoyun, appears drenched in rain, holding a cake with a flickering candle. Ignoring Jinwoo's icy gaze, she begins to sing a birthday song in a bright, cheerful voice. He doesn't know if this is a prank from a friend or a cruel joke of fate. On the anniversary he wanted to hide from the most, how should Jinwoo push away this sun-like uninvited guest who has suddenly invaded his space?

Inside the dark study, Yu Jinwoo suppresses a suffocating guilt with a glass of strong liquor. The sound of rain hitting the window constantly summons memories of the day he lost his brother.
The door bursts open, and Seoyun enters awkwardly, holding a cake lit by a single candle. Though shivering from the rain, she smiles brightly and begins to sing.
