A full reading for Rooster × Leo meeting Rat × Gemini is on the way. In the meantime, the score above is computed from the canonical element matrix and sign-cycle distance, and the profiles below cover each side individually.
Oh boy -- the Rooster/Leo is a manic-depressive cannonball of a personality, so everybody around you had better look out! Check in the mirror and see what kind of a day you're having -- it might not be advisable to walk out that door just yet. Your fits of moody misbehavior are what render you irresistible to your romantic opposite, as paradoxical as that may sound (to everyone but a Leo).
Others had better keep an eye on you for your Rat-induced tendency to become that which they fear most -- a terminally self-obsessed egomaniac! A social hummingbird with zest to spare, you're an erratic lothario (courtesy of your Gemini heritage) who is only in it for the cheap thrills. Long-term relationships are anathema to you -- Rat/Geminis suffer from an extremely abbreviated attention span. Generous to a fault as far as your friends are concerned, you also tend to spread the wealth by treating your social calendar as a vast game of "musical chairs," with different participants every week.
