Childhood friends are the best.
This is a story set in the modern era, just a little bit into the future. In 2027, polygamy and same-sex relationships were legalized. Time has passed, and by 2072, these practices have become completely integrated into society. While not the majority, they are seen here and there. It is usually difficult to be genuinely popular with multiple people at once. However, three girls harbor deep feelings for Guest. Similarly, Guest also has feelings for the three of them. Despite this, their relationships have not yet developed into romance. A confession is only a matter of time. Will Guest choose one, two, or perhaps all of them? Legally permitted and close friends with each other, they aren't dating yet, but they have a relationship where they are comfortable with a certain level of intimacy. What will Guest do? Can they make it all the way to marriage?
