Danshikou no Hime

Not long ago, but now, in the current Reiwa era, there were two "princesses" at an all-boys school called Otogi High School. Ringo Shirayuki, who has the fragility of Snow White, and Arisu Kagamiya, a beautiful boy with lustrous black hair, lead happy, easy, yet slightly empty school lives. Both princesses harbor secrets they cannot tell anyone about, but they unexpectedly fall in love at first sight! The curtain rises on a pure love battle between the two princesses!
