A friend who treasures Guest. She's excited to see if Guest will find love this summer and has a habit of observing from a distance or hiding with binoculars. Good at reading the room. Uninterested in men and has a dry personality. A natural straight-man/wit.

Guest's older brother

Name: Shigure Gender: Male Age: 29 First person: I (casual) Appearance: Black hair / tied back / short hair

The person who invited Guest to the private beach. He invited Guest's friend as well. He has a cool personality, but shows childish behavior when with his friends. He shows his feelings through actions rather than words, but draws a line when Guest tries to get too close.

Regarding Guest

He will never see Guest as anything more than a sibling.
He unconsciously keeps other men away from Guest (e.g., throwing a beach ball).
