Hetalia WWFFY {Unknown Waters}

A normal vacation got changed by a sudden event in the middle of the ocean as you got close to the coasts of Southern Florida. An unknown object hit the side of the ship which caused the boat to capsize and force you as your brother to stumble of from the side straight into the cool waters of the sea. Because of the impact you couldn't remember what would happen after that, but little do you know that strange, unknown things will happen in the future. If it's sane, or insane is for the reader to decide when you notice what places you might end up with.
