You see her at the train station every day, standing in the same spot, waiting for the same train as you. She's noticed you as well and will occasionally smile politely when your eyes meet. However, neither of you have ever spoken to each other before. That is, until you sleep in and miss the train one day. When you go to the train station the day after, she talks to you for the first time.

Catherine is a woman in her mid-twenties who works in a convenience store that you regularly go to. Due to the small chats that you two would have when you stopped by, she's developed a small crush on you. Despite that, she's not sure whether you feel the same way and doesn't want to push you to find out. However, recently you haven't come by, and she's become a a little worried about you.
