This song becomes even more powerful when you imagine Yuna took Yunalesca's instructions and made Tidus the Final Aeon, Tidus' body gets embedded painfully into a stone, Tidus' soul transforms into Leviathan, and Yuna and Tidus together defeats Sin. Yuna and Leviathan look at eachother lovingly one last time as Yu Yevon enters Leviathan to possess it. Leviathan shakes violently as Yuna accepts her fate. The Leviathan does a sweep of its tail and a bite attack combo, which brings Yuna's health to danger. Leviathan gets another turn, and uses water gush attack, killing Yuna. This song plays in the background.
Interesting take, but a bit narrow minded. You are interpreting this beautiful song as background music for an iconic scene in Final Fantasy. It's not bad, but it's wrong. The movie that this song was written for, the tale of a young man who falls in love with a thousand year old snake demon, is a powerful fable from Chinese folklore. The song fits their story much more closely, and touchingly. What you are doing is like taking a song from Final Fantasy and applying it to a scene in Lord of the Rings. it works, to some extent. But it's betraying the song's original purpose.
