Rat/Capricorn and Ox/Sagittarius pair at 65-70%, a fully cross match between a solitary power climber and a performer who lives life in public. One prefers the cold quiet at the top; the other cannot function without an audience.
Ox/Sagittarius is a born coupler, fiery, flattering, always mid-relationship, sometimes before the last one ends. Rat/Capricorn wants to be loved for its bad Capricorn self alone, not for position or possessions. The Ox's sincere flattery feels wonderful and suspicious at once, which keeps the Rat both hooked and wary.
Ox/Sagittarius sings like a canary, narrating every drama; Rat/Capricorn measures words like currency. The Rat hears smoke screen in the Ox's charm, the Ox hears coldness in the Rat's silence, so both must learn to say the plain thing.
Friction sparks over loyalty and limelight. The Ox's public dramas and overlapping attachments alarm a Rat already braced for betrayal, while the Rat's naked focus on the next climb leaves the Ox playing to an empty seat.
Ox/Sagittarius warms Rat/Capricorn's brutal solitary serenity into something livable, proof that being watched is not being judged. Rat/Capricorn gives Ox/Sagittarius structure and a reason to finish one story before starting the next.
At 65-70%, Rat/Capricorn and Ox/Sagittarius are workable with effort: real heat and real ambition, but trust must be built faster than either sign's habits erode it.
