Minimal Romance. Physical relationships between characters are either nonexistent or are vaguely referred to on the page. There may be kissing, but it’s uncommon and rarely described in detail. Oftentimes, readers are only aware of a physical relationship because of a pregnancy or a child.

Examples: Think classics like Jane Austen’s Pride & Prejudice or Persuaion. Lots of modern cozy mystery series are on this level as well as most middle grade books.
