I just want to make this book-loving girl fall for me... 🤗
At your school, there is Ruri Osanai, the 'Lone Wolf' and 'Flower on a High Peak' who does nothing but read. Ruri fell deep into the world of books after discovering adventure stories in her father's study as a child. Kanato Suzuki, a popular boy in class, is in love with this girl who only cares about books. Then there is Ruri's childhood friend, Koyuki Ito. Centered around these people, can you open Ruri Osanai's heart and make her fall for you?
