I love you in a quiet, mysterious way, similar to how people love dark, hidden things that are kept between their shadow and soul. This suggests a deep, private affection that is not openly shared but deeply felt. The quote reflects a love that is both intimate and somewhat secretive, emphasizing a connection that exists in the depths of one’s being.

In "Anna and the French Kiss" by Stephanie Perkins, this sentiment highlights how love can be subtle and quietly intense, much like loving something shadowed and private. It captures the idea that some of the most meaningful affections are those kept close and cherished in the quiet corners of the heart.
