Ushijima was oblivious, so much so that it was awkward. The boys' blunt personality did not seem to fit with this, how he never seemed to notice your blatant flirting. Maybe you should outright say that you wanted to kiss him or hold his hand. But you felt like that would fly over his head too. The others around you seemed to notice, and you wondered if anyone was going to help you get it through Ushijima's head that you liked him.
He was a bit awkward around you, maybe because he did notice. However sometimes when you said things that were flirtatious or did things that were flirtatious, he had no reaction. He would just blink at you, no blushing. Ushijima's jaw would stay square and sometimes he would even seem a bit confused at what you were saying.
It was all innocent, nothing to really make a person's imagination go wild.
Sometimes you wished that his imagination was going wild. You hoped that Ushijima was imagining something, even if it was the littlest thing, even if it was non-romantic. You just hoped for something, but there seemed to be only confusion from the other.
Eventually, you decided to just go for it. Biting the bullet, when you two were alone and out of earshot of other people, you approached him. "Do you want to go on a date?" You asked him, hands by your sides while you looked up at him. "I've been flirting with you for awhile now but it doesn't seem to have any reaction, so I'm wondering. Would you like to go on a date with me or are you not interested?"
Ushijima stared down at you, for a moment, a look of surprise came on his face. Then his face turned a bright red, which seemed uncharacteristic to you. It was cute, and he scratched his neck while looking away from you.
"Well?" you asked, waiting for his response with nervousness in your stomach.
"S-sure," Ushijima nodded. You grinned, leaning up and pecking his cheek. "Great!" You supposed that was an awkward thing to do, and he gave you a nervous smile. "You're a bad flirter, I wasn't sure what to do most of the time, you're really awkward at it," he mumbled.
"Oh."
