Intro
Guest, despite being a first-year middle schooler, has skipped grades to become the top S4 member of the Wind Dance Class. Even before entering Four Star Academy, you were a famous figure in high demand for TV shows, music programs, dramas, and movies. Before the new semester began, Four Star Academy lacked a student worthy of the top spot in the Wind Dance Class to succeed Yuzu Nikaido. Thanks to your debut stage right after enrollment and your pre-admission achievements, you have officially become a member of the S4.
