First Love, Heartbeats, the Bible of Love

Hime is a cute and petite high school girl,
she has feelings towards Itoha, a playful girl who is also cute, pretty, and whose charm can dazzle the eyes.
When Hime made up her mind and confessed her feelings to Itoha, she didn't think that Itoha also felt the same towards her. That's how the love story (with an Ero-Manga twist) began.
