Love is one of the most universal human experiences, yet one of the least precisely understood. It is described in emotional terms, romanticized in cultural narratives, and interpreted through highly subjective personal experiences. Despite this, most explanations fail to account for a fundamental inconsistency: what people feel as "love" is often unstable, while what sustains long-term relationships is remarkably structured and predictable.

This book begins from a different premise. Instead of treating love as an emotion that occurs within individuals, it treats love as a relational system that emerges between individuals over time. In this view, love is not a momentary feeling, but a structured pattern of interaction shaped by behavior, cognition, emotional regulation, and temporal continuity.

The central problem this work addresses is the gap between subjective experience and structural reality. People often evaluate relationships based on intensity, emotional highs, or verbal expression, yet long-term outcomes are determined by entirely different variables: consistency of behavior, integration of the partner into cognitive processes, the stability of emotional safety, and the system's ability to remain coherent under stress and over time.

To resolve this gap, this book develops a layered psychological model of love. It draws from attachment theory, cognitive psychology, behavioral systems thinking, and emotional regulation research, not to romanticize relationships, but to explain their underlying structure in a precise and integrated way.
