There are five, all from the perspectives of different Tantalus members, focusing on Zidane. Some ending spoilers.
He never fell, never even stumbled. Most children learn to walk by taking small steps, but he could run and climb as soon as he found out what his legs were for. Maybe it was the tail - Burmecians were said to have good balance, too. All Baku knew was that Zidane was sure-footed, and sure-hearted. The boy never strayed from his chosen path...even when that path chased after a troubled girl who was high above his reach.
Baku gave his son a good thrashing, to make sure that he was serious, and then watched him go his own way.

That princess that sure as hell done a number on Zidane. Blank had never seen him like this - the guy got shot down all the time (it happened when you flirted with so many girls that you couldn't keep their names straight) but he always got right back up and tried again. Now his normally-cheerful little brother was thrown so off-balance that it was almost physically painful to watch. The guy had fallen, and fallen hard.
It was obvious that he didn't want his family's advice, so Blank just let him be. He'd pick himself back up soon enough.

They'd all thought he was dead. When the Iifa Tree collapsed on itself with the genome brothers inside - well, not even the queen had held out much hope. But then the man came staggering into the hideout, months later. He looked like he'd been through hell, but his smile was the same. All he did was talk about her - and by the time he looked like himself again, Marcus had an idea.
“They say the queen still loves plays. She was Cornelia once - let's give her back her Marcus, shall we?” Zidane grinned, and never faltered.

Ruby sniffled from offstage, makeup running down her cheeks. The queen had come a long way from the quiet young thing that the boys had kidnapped - she punched Zidane for making her wait even though she was laughing and crying the entire time. The stupid boy was obviously confused, but he did the right thing - grabbed her and held her close.
She clung to him like he was all that was keeping her upright, and there was so much love in her eyes that Ruby burst into tears all over again at the sheer romance of it all.

They had some weird-looking kids, that was for sure. Tails and horns and bright, inquisitive eyes. Cinna made a point to go visit them often - it wasn't like any of his other Tantalus brothers were going to be getting married any time soon! Plus, the castle always had good coffee.
Zidane still didn't look completely comfortable as the queen's consort, and he still wandered off, from time to time. The man had always had a taste for adventure. But somehow, he found a way to balance it all - a wife, a kingdom, a family, a life he loved.
