Aquarius on the inside, Gemini on the way in.
Your sun in Aquarius (air, fixed) is the engine — what thinks at the centre, what holds when you are at home in yourself. Your Gemini rising (air, mutable, ruled by Mercury) is the door — the way you arrive in a room, the first read the world takes of you, the body you walk in.
Strangers tend to assume you are witty and detached — that is the Gemini arriving first. Then they get to know you and discover the Aquarius air underneath, which can be reinforcing — same flavour, more of it.
Reads as Gemini until you trust them; then Aquarius comes through. The fixed-mutable mix means you holds on the inside while adapts on the outside — internal and external rhythms are different, which is its own work.
