Luck is simply probability, complicated and trivial maths say so, but is it? When you have a one in four chance to lose a bet, but still lose, is that just maths? When nine out of ten people die from a cotastraphe and you survive, is that just probability? No, of course not. Everything happens for a reason, so you lost for a reason, you survived for a reason... Right? The answer is, no one knows. Young Fei, a boy whose relationship with luck is beyond complicated, isn't satisfied with an unkown and he will stop at nothing to find his answers. But first he's going to jump off a cliff and see how his amazing luck saves him because why not?
