Ello Ello what's all this about?

My guess is that Misaka just received a present from the guy she adore, no?

Saten's supportive, as always.

Or could it be that she is going to give some chocolate to a certain boy?

If you were the receiving end of the chocolate, it'd be hard to react appropriately thanks to those two.

I have a strong suspicion the present is actually from Kuroko. Which makes Saten's behavior quite understandable.
