The person who fits you treats the two of you as a serious project — the kind with foundations. A Capricorn match means somebody actually decides: the restaurant, the savings plan, the year the house happens. The brick-by-boring-brick of it is not the price of the romance; it is the romance.
The cost is the office hours. Work will win some evenings it should not, and the feelings arrive filed under next quarter. The dry wit and the warm core are real, but both live behind a professionalism that can read as distance when you need mess.
What the match asks is that you take the long view they are already taking, and pull them off the mountain on schedule. Respect the ambition, insist on the rest days, and the structure you build together will still be standing when the exciting people have all moved on.
