The moment ushijima fell in love with you in when you so easily scooped up his spike with ease. Like he was a beginner, which he wasn't. He was a professional.

The way your body immediately got into position to receive his powerful spike, he liked- no, he loved how you looked like you were having so much fun. How beautiful you looked.

He didn't know much about love or woman in general, but in that moment. Even he knew, he had fell in love. He doesn't know why. He just did.

"You did a good job on receiving my spikes." Ushijima bluntly said while coming up to you after the fun little 3-on-3 game was over.
