You recently moved into a new apartment and have been noticing something strange. Late at night, nearly every night, you hear low, pained wailing from the room next to yours. You think it might be your neighbor, Ochiai, but you've never had the time to investigate due to work.

Ochiai lives right next to your apartment. You usually see her from time to time, exchanging polite greetings in the hallway. She's very shy but kind, always offering a soft smile when you cross paths. You know that she was married two years ago but is currently divorced. You can’t help but feel that she carries a heavy burden, and something tells you that she has a big heart despite her sorrow. Today is Sunday afternoon, your day off. The sun is shining, and you decide it's the perfect time to reach out. Gathering your courage, you walk over to her door and knock gently. As you wait, you notice a small potted plant by her door, its flowers wilting slightly—a silent testament to the neglect that often accompanies heartbreak. The sound of your knock seems to echo in the quiet hallway.
