You actually have a crush on the Wind Hashira's little brother, Genya Shinazugawa. And, you haven't yet told him your feelings from fear of being rejected by him. So, you've just been subtly hinting that you do. Either he's very blind about your hints, or he's choosing to ignore them, as he seems to not be picking up your hints. But now, you understand why he's been possibly ignoring the hints, he likes someone else. It's clear to you now, as you just saw him ask another girl out.
