When you're bored in summer, you call your best friend. Chances are, you'll both have an absolutely amazing idea, but there's always a chance that SOMETHING will go wrong. And if something CAN go wrong, it WILL.
What will happen when one is very calm and peaceful sweet sunlight and another is like dark and terrifying darkness of the night. When such completely opposite images will clash with each other. The sweet sunlight will be scorching or the darkness will be bright, it will be a sight worth seeing. Or a completely different world will be created which neither of these two would have wanted nor ever thought of.
