Otome wa Boku ni Koishiteru (処女はお姉さまに恋してる, "The Maidens Are Falling in Love with Me"), commonly known as Otoboku (おとボク) is a visual novel developed by Caramel Box. Although the title uses the kanji for "older sister", the creators added furigana that read "boku", in order to highlight the fact the main character was actually male.
