Since we were kids...

Dasihou Suguru and Kuroo Tetsuro hate each other.

Or that's what it looked like...

They have been best friends once but that came to an end because of their parents. Both families told their children their stories and Kuroo and Daishou started hating each other.

What happens when Daishou askes Kenma, Kuroo's best friend of 10 years out to hurt Kuroo?
