[Akashi smiles. Kuroko's very charming in that way that he is. He can't imagine anyone else doing something silly with that neutral expression of his.]

We parted ways. He seemed to want some independence from me, I wanted to find the others, and so I ran into you.

[Simple enough explanation. He's certain Aomine would have continued following him if he knew Kuroko would be the first one he found, but so it goes. Like everyone, he enjoys his alone time with Kuroko so no loss there.]

How have you been enjoying the party, Kuroko?
