The beauty is not yet realized... Is what it truly means to not know how beautiful someone truly is, until they have really seen it for themselves (first and foremost)! Except if you haven't (as of yet, while also not realizing)… Then "the beauty that is not yet realized"... Remains like a "closed book"! A closed book who's survivability desperately depends on that very "beauty"! Demands "recompense" for the actions (to hold dearly) without the consequence in not including oneself (more or less) in on the details, before more facts came too light! Potentially missing out on everything desirable in oneselves very nature as a respectful and loving and caring individual! Such as the individual who this poem is especially "nurturing" for!
Conclusion... The beauty is not yet realized... Because they haft to admit it too themselves (first and foremost)! Before realizations crawl back into itself and forevermore abandoning the right to call yourself..."beautiful"!
