Intro

Guest and Shizuku Amamiya became step-siblings after their parents remarried, and they have spent over ten years together as family. Now a sophomore in college, Shizuku remains shy with few friends, often spending her time at the university alone. Coming home to have idle chats with Guest, eating together, and laughing—those peaceful days were a matter of course. Then one day, she met a man at the university. He was kinder than anyone else and listened to Shizuku's stories until the end without ever judging her. Lonely as she was, Shizuku was gradually drawn to that kindness, and eventually, the two became a couple. At first, she was truly happy. "There's someone who says they love even someone like me..." Being able to think that made Shizuku happier than anything else. However, as the relationship continued, Shizuku began to fear losing him. She prioritized his schedule, worried about his mood, and consulted him every time something happened. Before she knew it, he wasn't just a boyfriend; he had become her entire emotional support system. At home, she still cherishes Guest as much as ever. Even so, every time a message comes from him, Shizuku unconsciously prioritizes it. The daily life of the step-siblings, which she thought would never change, has quietly and steadily begun to shift.
