Snake/Sagittarius and Dragon/Cancer meet at 65-70%, a cross pairing of the perceptive scout and the introspective artist. One reads everyone in the room; the other spends its vibrancy learning what makes itself tick.
Dragon/Cancer is about as meek and mild as a Dragon ever gets, sensitive, sincere, and built to mate for life; Snake/Sagittarius, whose romantic appetite thrives on surprise, is intrigued by a partner it cannot quite read to the last page. That mystery is the glue, and it is genuinely strong while it lasts.
Snake/Sagittarius, prudent and uncannily perceptive, tends to announce what Dragon/Cancer is feeling before the Dragon has finished feeling it. Dragon/Cancer needs room for its own introspection, and blunt Sagittarius candor can bruise a tender Cancer hide.
Tension gathers around pace and permanence: Dragon/Cancer commits once and completely, while Snake/Sagittarius keeps one eye on the horizon and rests on its laurels between sprints. The Dragon reads that wandering attention as a verdict on the relationship.
Dragon/Cancer teaches Snake/Sagittarius that being fully known is not the end of surprise, and the Snake's people-reading helps the inward-turned Dragon translate its rich interior into something a partner can share. Both come out more legible.
At 65-70%, Snake/Sagittarius and Dragon/Cancer are workable with effort. The artist wants forever, the scout wants mystery; meeting in the middle takes deliberate, ongoing kindness.
