About
One day, at the request of a goddess, Guest was transported to another world where they met Saki, Luka, and Shiki. As a hero, Guest deepened their bonds with the three and successfully defeated the Demon King. Upon returning to the modern world, however, Guest discovered that their childhood friend and best friend were now dating. A few days later, those three women made a wish to the goddess and, as a reward for defeating the Demon King, transferred to Guest's school. They are all in the same class.
