Leo had always had itchy feet. He had seen countless planets, stars, moons, and asteroids. He wasn't picky, if there was life on it, then chances were he'd stop by the and take a look. He, together with his friends Odin and Niles, roamed the infinite reaches of space, or at least the inhabited parts of it, in the Brynhildr, their trusty ship. They had done a bit of everything, together they had become smugglers, pirates, and mercenaries, they had gotten in bar fights, space fights, and everything in between. Leo never liked to stay in any one place too long, he always pushed their ship onward to new places and new sights. Most of the time he felt that he'd never want to settle down in life and stop his rootless lifestyle.
He had first left home to put as much distance as possible between him and his brother, "Mr. Perfect". Leo had wanted to do nothing more than to escape Xander's shadow. So, where Xander stayed like the dutiful son that he was, Leo left; where Xander's sole motivation in life seemed to be furthering the glory of Nohr, Leo's was self preservation; where Xander lived life in terms of black and white, Leo lived in the fuzzy grey area in between. Though their journey had started as an effort to get as far away from Nohr as possible, it later morphed into getting as much distance between them and the scene of their last heist. They didn't achieve widespread infamy by a long shot during their various exploits, but their were a few bars in some of the more tattered areas of space in which people spoke of their exploits in hushed voices.
They had no plan that they followed when going from place to place, the only rule was that they never visited the same place twice. So eventually, what with one thing and another, the gang ended up on the planet of Hoshido, Nohr's archenemy. It was there that Leo met the person that convinced him that maybe there were perks to settling down after all.
He first noticed her in the hospital. Odin had developed a case of food poisoning and it wasn't until he started throwing up that Leo and Niles realized that Odin was being serious and that he wasn't just making stuff up about the darkness in his blood again. She was slight in stature and had pink hair, that was all Leo noticed because she was also up to her eyeballs in people asking her to do things. Leo was smitten. Niles took one look at him and promptly started teasing him about it. He didn't see her again until Odin got out of the hospital, and he "ran into" her at a coffee shop and managed to strike up conversation without looking like a complete fool.
Her name was Sakura, Leo was falling for even more than he had been before.
They met again and again, he learned that she was the youngest and that they shared some common interests in books. He told her of his adventures in space while she listened raptly. She told about her everyday life, it wasn't adventurous like Leo's but he liked listening nonetheless.
The more he got to know her, the more appealing the thought of settling down became. Maybe his spacefaring days were over.
Niles asked when when they would be leaving. Hoshido was meant to be a quick stop. They had stayed for a month. Leo told him that he could leave on his own. Staying was becoming more and more appealing every day. Odin and Niles left on their own, they told him that if he ever called they'd come and pick him up. Leo listened politely and said he'd keep that in mind, but leaving Hoshido was the last thing that he wanted to do right now.
The more time he spent Sakura the more he liked her. He began to think that all the distance that he traveled was just to find her. Let Xander marry a Nohrian woman, he thinks, he's happy with his own little Hoshidan flower.
AN: This started as a soul mate AU where everyone knew how far away from their soul mate was. It turned out really different from the original concept. But, it still kind of fits the prompt. Also, there need to be more science fiction AUs out there. Where are my spaceships?
