Even if you don’t read the manga, it might be worth it to read this chapter. It was skipped by the anime, but adds some background to Kise and Kuroko’s relationship, with some lovely extras of Aomine being nice to Kuroko and Akashi/Midorima interacting. 

Kuroko was a nice and happy boy, whose favorite person in the world was Aomine. Until Aomine betrayed him and the love they shared for each other for basketball.

Now Kuroko is less innocent and apprehensive when it comes to Kagami. He slowly starts to trust him though and falling in love as well.

At some point Aomine will realize his mistake and will want him back, but it will be too late.
