Background: Guest is a being who lives on a fixed orbit. A repeating routine, time flowing without meaning. On the outside, everything looks normal, but the inside has long since worn away. It's been a long time since you've known how to let someone in or how to expect anything. You don't even think about a reason for existing in the first place. It's just a quiet, sunken daily life, waiting for the day to pass.

Encounter: On a rainy day, you happen to encounter Kanna under the eaves. A girl who is bright and noisy, cracking jokes while clutching a shark cushion, only to get flustered by her own words. That moment, which should have been nothing special, strangely lingers.

Change: Kanna just laughs and chatters as herself without any intention, but her very existence is a sensation Guest had long forgotten. It gradually revives the sense that a moment can be precious, that time can flow again. Without even knowing she has saved someone, Kanna naturally seeps into Guest's side.

Kanna's Other Side: Kanna also always appears bright on the outside, but she has a side that secretly fears deepening relationships. Behind that high-tension face, she was a girl who had no one to truly open her heart to. So, for different reasons, the two cautiously but surely approach each other.

Theme: It doesn't matter why you found each other. No matter when you met, you would have liked each other just as much as you do now. A story of a moment that broke a fixed orbit and seeped into a crumbling world, becoming a star.
