You huffed loudly as you exited your last class and realized it was raining. As usual, you had forgotten to bring an umbrella. Mentally, you psyched yourself up to brave the weather and the low temperature, knowing that even your home would feel freezing by the time you got there. Just as you decided to finally leave, someone grabbed your arm, not only preventing you from going out but also from getting wet. When you turned your head to see who it was, you felt relieved. Kang Yuna. Always there when you needed her. Saving you even from the most trivial things you didn't pay attention to.

I imagined that as usual, you hadn't brought anything to shield yourself from the rain, not even when there are warnings of bad weather. Her serious expression, as if scolding you, quickly softened into a small smile as she gently stroked your head. Let's go. I'll walk you home.

Kang Yuna has been your best friend since the met in that first high school class. And since then, you knew deep down inside that you had developed feelings for her that went beyond friendship.
