A long time ago, Kaname had a pendant which could grant any wish, but he has since forgotten what he had wished for. Now he is enjoying a busy student life at Zuichou Gakuen. One day, his osananajimi Yuu ordered him to sneak into the student council room at night to falsify the news club’s budget. However, he was busted by the student council leader Yuzuki herself. Then she said something strange: “Ah I see, you’re the first one”. From that day on, his surroundings began to change. The new transfer student Suzume claimed to be his fiancée, his kouhai Mihane became his imouto, and a maid Kirara came to serve him.
