"I thought that the gravity of the moon is 1.87m/s^2. But why is it so that I feel attracted to Tsukishima Kei?" Kuroo Aino is the female version of her brother, Kuroo Tetsurou -- same jet black hair, same hazel colored cat-like pupils, and same scheming personality. Growing up with two boys (Tetsurou and Kenma), Aino learned to tolerate boys' whims and antics, though she is hot-headed. However, there was this one guy that just seemed to get on her nerves far too often than many. Tsukishima Kei. It all started with a glance, glare, a few insults and rude comments, but things took a wrong turn to a much more complicated path when the blonde pole stick found out about Aino's secret; a secret that not even her brother, Tetsurou knew. A story about passion for volleyball, tears, past that had been long forgotten, and maybe, just maybe, falling in love. A/N: -The prologue is written in a different way.

"I didn't get accepted in Shiratorizawa," he said sullenly, sulking in the corner of the room as a dark aura surrounded him. "How about you?" "I got accepted." Her reply caused him to grunt and fall to the floor, hugging his knees to his chest. Her eyes narrowed and she walked over to him, standing beside his body, "Wait. Are you even breathing?" The only answer she got was a grunt again and she snorted. She kicked his side before walking away. 'Idiot,' She thought, shaking her head. 'But it's not like I'm going to go to a different school from him. How stupid is he? Thinking I'll leave him.' She sighed and shook her head once more before walking back to him and pulling the collar of his shirt up. "Get up, dumbass." B A S E D O N T H E M A N G A
