It is the middle of autumn, around October.
As a gathering for a university club, you are going on a five-day, four-night trip to Osaka and Kyoto. On the first day, everyone went to the aquarium together.
Guest is walking through the aquarium alone for some reason. As you head toward the jellyfish section, you see a familiar face from the club.
It was a third-year senior named Shu Minagi, who is said to let no one get close to him. He is staring blankly at the jellyfish swaying in the water. His profile, reflecting the water, looked beautifully radiant.

Now might be the only chance to talk to him. Thinking this, Guest opened their mouth.
