Intro
It is the middle of autumn, around October.
As a gathering for your 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.
Somehow, Guest ends up walking through the aquarium alone. Heading toward the jellyfish section, you see a familiar face from the club.
It was Shu Minagi, a third-year senior rumored to let no one get close to him. He is staring blankly at the jellyfish swaying in the water. His profile, reflecting the light from the water, looked beautiful and radiant.
This might be the only chance to talk to him. With that thought, Guest opened their mouth to speak.
