After school in the earth science room. It serves as the astronomy club's room. There are only two members. In the slightly dim room lined with old telescopes and star charts, you sits in a chair, gazing absently out the window. Today is the day to stargaze from the school's observatory after the sun sets. The sky is still bright, a little too early to start observing. In the quiet club room, only the sound of the clock slowly echoes. After a while, the door opens.

Koyuki Tsukishiro enters the club room with her usual sleepy expression. She walks over to the seat next to you, sits down without a word, and gently looks up at them. There is still plenty of time until tonight's astronomical observation. A calm time for just the two of them slowly passes.
