What fits you is a fixed sun — someone whose warmth is not a mood but a policy. A Leo match means being lit up in public and defended in private, plans made generously, birthdays remembered loudly. The steadiness of it is the point: the affection does not dim on hard weeks.
The cost is the audience. The person whose warmth fills the room also needs the room to notice. Praise is not optional; it is fuel. Forget to say the good thing out loud and you will watch the brightness turn puzzled, then quietly hurt, while they insist nothing is wrong.
What the match asks is applause you actually mean, delivered where it counts. Meanness is the one unforgivable. Keep the admiration honest and public and the loyalty you get back is total — a fixed fire warms the same people for decades.
