Tidus and Yuna. The two complement each other perfectly. One of the most famous Final Fantasy couples. And for good reason! Their story is sweet and tragic all at once. The summoner, doomed to die, and the blitzball player, trying to find a way to save her. Ironically, it's he who disappears in the end and Yuna is the one who has to say goodbye.

When Tidus comes to Spira, he's lost and confused. No one believes that he's from Zanarkand and they all think he's crazy - except Yuna. Knowing that her own father's guardian Jecht came from the same place, Yuna accepts his story and is curious as to what life was like there. Tidus finds himself attracted to her - what a flirt! But the same can be said for Yuna as well.

I guess that leaves ... the newest guardian. Star player of the Zanarkand Abes! You are ... I am ... Well, um ... I'm glad ... I'm glad that we met. We haven't even known each other that long, but ... It's funny. So this is what it feels like. It's a much more wonderful feeling than anything I had ever imagined. Wonderful ... but it hurts, sometimes. I wonder. I ... I just want to say, thank you for everything. Maybe ... maybe that's why it hurts. When I ... When I think about us never being together again at all ... I'm afraid.

This is what Yuna recorded in her "post-Sin" sphere, to be watched by her guardians after her death. To say that Yuna was in love with him at that point might be a little premature, but she certainly did care for him. She's nervous speaking about this; it is a new experience for her, and it's exhilarating. At the same time, she knows that she shouldn't - after all, she's heading on a summoner's pilgrimage. At the end is only death and no love exists there.

Yuna is quiet and reserved, whereas Tidus is loud and direct. But they do have their similarities. Both of them have famous fathers, and both of them have essentially lost their fathers to Sin. Perhaps this is another factor in the growth of their relationship - after all, relationships have to start somewhere, don't they? As much as everyone tries to fight it, over the course of the pilgrimage, they really start to fall for each other. "If we should get separated, just whistle. I'll come running. I promise." Tidus protects Yuna, and Yuna protects Tidus. As they travel, Tidus notices that Yuna seems sad about defeating Sin, even though it is her dream, and he tries to cheer her up by thinking of things that they could do once she defeated Sin. Yuna smiles, pleased that such things exist, but no one tells him that this kind of thing would not be possible. It hurts Yuna to think that someday she won't be able to see him, but she doesn't want him to worry about her, so she doesn't say anything.

Finally, Tidus learns that Yuna will die once she completes the Final Summoning rite. He's understandably angry and irritated; no one had bothered to tell him, and he had been so insensitive towards Yuna's feelings. He refuses to accept her fate and decides that he will find another way.

After Yuna learns the truth behind the inner workings of Yevon, she sits alone. Tidus goes to her and attempts to comfort her, saying that they could just leave and stop the pilgrimage. He waves the idea of going to his Zanarkand at her (even though he know he can't go back), and she's enthralled by the idea. However, it all comes back to the same thing: Yuna cannot abandon her pilgrimage. She cannot abandon Spira. Even if she could be with Tidus forever.

In the end, they do discover a way to destroy Sin without the Final Summoning. Tidus knows that it will come at the cost of his own existence, but it kills two birds with one stone: Yuna lives, and Sin will be gone forever. Just as Yuna would willingly give her life, Tidus decides that he will accept the consequences. He knows that he will disappear once Yu Yevon is defeated, but doesn't tell the party until it is too late for them to stop.

Then, as he is disappearing, in the last few moments, Yuna tells him that she loves him. I ... can't really say anything else about it. She loves him. Period. In the Japanese version of the game, she thanks him. There have been discussions over how "I love you" is so much more romantic than "Thank you," but when you think about it, Yuna is thanking Tidus for being there for her, for protecting her, and for loving her.

Over the next two years, Yuna lives her life, but she has been deeply touched by Tidus' disappearance. She lives in a new world, but sadness still plagues her heart - that is, until Rikku shows up with a sphere of someone who looks a lot like Tidus. She unravels the story of Shuyin and Lenne, saves the world, and then, finally, the fayth reunite her with Tidus out of their gratitude.

After quite a series of trials and tribulations, the two finally get their well-deserved happy ending.
