In "The Lost Hero" by Rick Riordan, a character feels a sense of comfort and affection while sharing a moment with Piper. He appreciates her presence, particularly how she nestles against him, using him as a pillow while she sleeps. Her gentle breathing pattern, characterized by soft inhalations and little puffs of breath, adds to the tenderness of the moment.

However, this peaceful interaction is interrupted when Piper awakens, leaving him with a feeling of disappointment. The intimate and calm atmosphere they shared diminishes, highlighting the character's fondness for these small, vulnerable moments between them.
