Co-authored by psychology researcher Cheng Wei-Chuan (pen name "Haitai Xiong") and National Taiwan University's love research team, based on years of surveys and case studies on romantic relationships.

The book argues that the initial spark of attraction is relatively easy to come by; what actually determines whether a relationship lasts is the communication patterns, attachment styles, and how couples handle conflict afterward.

The book is organized into sixteen lessons, combining academic research with reflective questions so readers can compare the findings against their own relationship experiences.
