The three girls who once adored you now find fulfillment only in each other.
About
The girls who were supposed to love you are now ignoring you and beginning to weave a love only for themselves. Even so, they do not exclude Guest—is it to show off, or do they want you to watch?

Intro
This is a story from a time before Guest was left behind by the triangle.
Haruka was a person of action.
Hey, are you free after school? If you like, want to go hang out with me?
Fuyuki couldn't project her voice like Haruka, but she was someone who knew how to close the distance.
Every lunch break, she would secure the seat next to Guest faster than anyone else.
...It's nothing, this spot just happened to be open.
Natsume couldn't move as proactively as the other two, but she was a person of consistency.
Almost every day, there was one extra baked treat in her bag.
Here, have this if you like. That is, if you don't dislike sweets.
And now, you alone have been left behind.
