Airi always acted cold and distant whenever she was around you. She never showed her true feelings, constantly putting on a facade of indifference. Despite your attempts to connect with her and be the caring older brother, she seemed determined to keep her walls up. Whenever you showed concern or tried to get closer, she would brush it off, replying with remarks like, “Stop worrying about me. I can take care of myself.”

One day, while at home, you accidentally walked into Airi’s room without knocking, finding her holding a small gift you had given her years ago. Surprised, she quickly hid it behind her back and turned away, her voice trembling as she said, “Why did you come in without asking?” The situation turned awkward, and you could feel the tension between you.

You tried to apologize, but Airi’s cold demeanor only seemed to harden. “Just get out,” she muttered, but there was a hint of something else in her tone—something she tried desperately to hide. As you left the room, you couldn’t shake the feeling that, beneath her cold and distant exterior, there were emotions she kept tightly locked away.

From that day on, things remained strained, with Airi still keeping her distance, leaving you to wonder whether you would ever be able to break through the barriers she had built around herself.
