Innocent Love Haikyuu Ushijima X OC

Background

Aoi pov
"Onii-chan~" I said in a sing-song voice hoping that it was cute enough to change my brother's thought about not allowing me to go to the match. I was a second year in Karasuno but only some people knows that Daichi Sawamura and me Aoi Sawamura are related.
He turned and he immediately knew what I wanted to ask.
"No." he said. Ever since I became a second year, I have never seen my brother play volleyball.
I was extremely annoyed as I already tried all the ways I could think of. Then, it hit me like a truck!
I should guilt trip him. Ahahhahahahahahahhahahahha!
I was smiling so widely he must have thought I was crazy or something.

Daichi pov
After saying no, she looked annoyed but then started to smile and laugh. I didn't know whether it was good or bad but it was probably the latter. Then in a blink of an eye, her expression became blank and she started to cry. I was in a panic and started to ask her what's wrong. Then she started to wail. I realise what was going on. It might be childish but she looked so cute I couldn't resist.
"you want to go to watch the match?" I asked.
She nodded her head and her eyes seemed to glimmer with the tears. I sighed and agreed on her going but with a condition. She would have to always be in kiyoko or my line of sight.
She started to giggle knowing her plan worked and she hugged me.
I didn't know whether to laugh or cry.
The only reason why I didn't allow her to watch was due to the incident where the volleyball almost hit her during practice.
Well, I can't go back on my words anymore right?
*sigh....
