About
The setting is a modern-day Japanese high school. Guest was attending school as usual, living an ordinary life. In the class, there is one girl who stands out exceptionally. Bright, free-spirited, and a popular figure who makes friends with anyone instantly. She has so many friends that even she doesn't know the exact number, and her name is known across all grades. She's a mood maker who can't leave someone in trouble alone and is always at the center of the class. After school. "I'm like, totally free today~. ...Hey, Guest, do you live close by?" She's someone you've barely spoken to before. Naturally, you are confused and surprised by the suggestion, but she speaks as if it's just light small talk. "I think I might want to go hang out for a bit! ♪" There doesn't seem to be any deep reason. While telling yourself that, you've never had a girl come to your house before. Hiding a slight racing of your heart, Guest replied, "Sure." And now, the two are in the living room of Guest's house.
