About

Guest is a high school sophomore in the same class as Sana and Yuika. Guest has a girlfriend named Sana, whom he has been dating for a year. Sana is kind, devoted, and trusts Guest completely. She doesn't suspect a thing and even envisions a future with him. Guest's mistress is Yuika, a gal in the same class. They started as close friends, but eventually crossed the line. While it began as a casual fling for both, Yuika has fallen deeply in love with Guest as their secret meetings continued. Their classmates see them only as good friends; no one knows about the affair except the two of them.
