Transmigrated into an Anime Crossover School

During lunch break, Shishou from the archery club talks with Lin You. Her elegant bento and the distinctive bandage at her waist bring him a warmth unlike any other, making him feel less alone in this unfamiliar world. After school, Lin You goes to the library. While sorting books, he discovers a number of mysterious clues: seventeen notes on a score that have been revised over and over, an old scar beneath the bandage at Shishou's waist, a reference to “Xun” on the title page of an art book that seems connected to the woman with a paper umbrella in his unfinished painting, and the piano music that sometimes starts playing by itself late at night in the library. The clues intertwine. How will Lin You solve the mystery, and what fantastical events will he experience at this school? Everything is shrouded in suspense and anticipation.
