Remember When Final Fantasy Was the Stuff?

Oh, the times where any jam session on the piano included having to play some Final Fantasy song like 'To Zanarkand", the times when I started drawing badly looking Yunas, Paiges and Rikkus all over my school work even if I never played the damn game. And it was like, 8 years ago and I had to stay at your house for a few weeks while my mum and dad was on holiday, and I watched you play Final Fantasy X-2. And then you showed me this clip of Yuna singing, and then you laughed at me because I was crying. But I assure you I wasn't, I was staring at the stupid TV screen (you know, back in the days when they weren't LCDs or plasma TVs) and my eyes started tearing up for staring at it for too long. I swear it isn't a excuse. I know it's funny though, it's like I'm cutting onions while watching Yuna sing.

Seriously, who's that girl with the long hair, why is Yuna singing? How the hell do I sympathise so much with Yuna by seeing her for the first time in my life give a emotional performance without the back context?
