I know nothing with any certainty

There will come a time in your life when you will become infatuated with a single soul. For this person, you’d do anything and not think twice about it. But when asked why, you have no answer. You’ll try your whole life to understand how a single person can affect you as much as they do. But you’ll never find out. And no matter how badly you hate it or how badly it hurts; you’ll love this person without regret, for the rest of your life.
