He's the son of a frontier lord and one of the few people naturally talented at wind magic. What really sets him apart, though, is that he wasn't intimidated by Yumiella—unlike basically everyone else at school. He initially started hanging around her because he genuinely thought her unorthodox methods would get someone killed, but he couldn't just stand by and let that happen.
Over time, his feelings for her deepened into something more serious, though he struggled to actually communicate that to her for a long while. He eventually managed to reach Level 99, which finally met Yumiella's (admittedly fake) criteria for a marriage partner—and things moved forward from there.
