A promise from a past life is made to meet in this one, yet due to the misalignment of time and space, and the reversal of yin and yang, we may brush past the right person in this life, or share a bed with the wrong one. Those who do not understand this will not comprehend the pain within. Even if happiness begins at the beginning, as if a lifetime together is assured, the tolerance of one or both parties will ultimately lead to incompleteness or even a permanent separation. Rather than saying it's an unintentional success, it's more accurate to say that what succeeds will eventually fail, and what fails will eventually succeed.
