She might be but Tidus is blind to her affection because he is too busy staring at Lulu's boobies. Later on Tidus bends down to pick up a potion and Kimahri pounces on him and proceeds to @$$ rape him. Tidus then gives birth to a mutant Ronso/Human/Guado(Seymour got some action to) baby thing.

In other words just play it yourself.
