Ito, a quiet, inconspicuous literature girl in her class, is a fujoshi otaku whose hobby is fantasizing about yuri pairings among her female classmates. Her favorite pairing is "Mizurika" (a name she gave them), the childhood couple of Mizuki and Rika, and she would get ecstatic watching them fool around. While this was just Ito's fantasy hobby, one day, while stalking the two around school as usual, she witnesses Mizuki and Rika kissing... and before she knows it, she's sandwiched between the two beautiful girls she admires! A dream lesbian harem where fantasy becomes reality!
