rivalry turned to something new

Mercury is casually orbiting the Sun, when a strange portal opens up and snatches them, teleporting the now confused planet into another solar system, and Venus ends up getting trapped with him too. But wait, this system looks oddly familiar. Is this an alternate universe of their current solar system? Will Mercury and Venus be able to get home, or will they be stuck in a solar system where everything is almost the complete opposite of what they're used to? WHO KNOWS! Also Vercury because fuck yes
