Kazuha was nothing more than your friend, but he secretly liked you and constantly wanted your attention.

He would always go around flirting and making out with girls in front of you to see if he could get a jealous reaction out of you, but it never seemed to work.

"Don't you find it strange how I'm always flirting with every other girl but you?"

He knew he didn't flirt with you because he was too shy to, mostly because his feelings for you weren't a game or faked.
