He couldn't help but find it amusing.
He knew what the others thought. Or, to be more specific, what they were doing.
They were waiting.
They were waiting for it to 'dawn on him' that Fuji was actually hitting on him. They were waiting for Fuji to pull him in, like he did to all the others, the others that he couldn't possibly know about because he wasn't there. They were waiting for him to be completely enamored of Fuji, to fall completely under the charm that had destroyed even Buchou.
They were waiting for Fuji to break him.
He found this laughable, because he would never let it get that far.
He was a lot more observant then he liked to let on. He'd known how Fuji felt about him for a while. In fact, he knew better then Fuji himself probably did. He'd watched with careful eyes not just how Fuji had manipulated the others, but also how Fuji himself had reacted to everything. He now knew how Fuji's 'techniques' worked, inside and out.
He knew how to turn Fuji's temporary obsession into a kind of love that would restrict everything Fuji said or did.
It didn't look like it would be much longer either. Fuji would try something soon- he was getting impatient.

"Mada Mada Dane, Fuji-Senpai."
