在上辈子，他不知道她爱他。直到那一刻，他才明白原来一切都非比寻常。他欠她一滴泪，但那是千年之后的事情。

他们的故事，跨越了三生三世。在恐龙灭绝后的世界，她给予他最甜美的果子和最精美的兽骨项链。但他，只是一位不知情的男子。他习以为常，不曾发现她的爱。

战争来临，他们战败了。她失去了自由，而他被杀。在异族人的刀下倒去，她哭泣。那一次，是唯一一次，当着他的面流泪。她为他哭泣过无数次，但只有这一次，他看见了。

她成了奴隶，等待着命运。而他，在死前，只有这一次，知道了一切都不寻常。他在心中说，我欠你一滴泪。但已经晚了，因为他的生命已尽。

再次轮回，她变成飞鸟，而他是一只游鱼。神许诺，他们将会相遇，但只能流泪一次。她为了见到他，无数次地衔石头投海，并抑制眼泪。直到最后，他终于倒下，那时他们相见，却再也没有机会流泪交换彼此的情感。

第三世，她成为了飞鸟，而他，一只小飞虫。她拜访神，得知这是最后一个机会。如果危难降临，他将穿金甲圣衣救她，然后还她那滴眼泪。这是他们姻缘的最后一年，他们必须抓住这一刻，因为如果错过，将永远分开。

但时间太长了，他们错过了太多次。冬天的一日，风告诉她，要等待在松树旁。当阳光灿烂之际，他发现自己快要死去，没有任何飞虫能度过冬天。他恨自己的短暂寿命，也恨自己迟缓理解她的爱意。

就在即将逝去之际，一棵松树 cried out, its tears a single drop of resin that enveloped him, preserving his life but rendering him immobile. This was their final cycle. No one could bear to watch them miss each other again.

As the years went by, she forgot about the past and found love anew. But he remained in his third lifetime, trapped in time with only a strand of amber connecting him to her. He watched as she lived happily with another man, filled with both envy and regret for not understanding sooner.

In the end, it was her who faced danger - trapped on a burning building's top floor. The fire god roared to consume yet another soul unaware of her impending doom.

He heard the call; still alive in his third lifetime. That moment brought back memories from centuries past: "In his third life... you will encounter peril... then he shall save you from water and fire... give you back that one tear."

She never heard; lost in a world beyond ancient legends' grasp.

But he remembered - and rushed into action without hesitation or voice for warning.

This time would be different; this time they would meet once more before fate tore them apart forevermore - if only there were enough moments left for them within their shared chronicles of yesteryear.

And so they met once more amidst chaos and flames as worlds collided around them while history unfolded like an unraveling tapestry woven from countless lifetimes spent yearning across vast expanses of space and time...

For every tale told has its beginning & end — no matter how long those journeys may last — & sometimes even after all is said & done there remains just one final thing owed between two souls whose paths intertwined through eternity's own twisted labyrinthine dance...

That single tear which had been promised since ages gone by now hung precariously upon the edge of existence ready to fall at last bringing closure to three lives bound together by love’s unyielding threads despite countless missed opportunities scattered throughout countless eons spanning millennia far beyond any mortal reckoning ever conceived — let alone realized!
