I don't understand

[Uehara Eisen. Morning.

Rizzuya. Elisbonear.]

"Hey, bastard. Why don't you let me join in on the fun?" The purple-eyed guy said. His voice carried sobriety that didn't exist before. The man stared at me with a blank face, devoid of all emotion. He simply stared at me as if our positions had changed. As if I was but a chore that he had to take care of.

It hurt my pride.

I pulled the redhead back and chained him to the wall again. I then unchained the purple-eyed guy's cuffs and moved away from him. The man sat in front of me, his gaze still the same. Was he good at Go, or was this just a facade?

I separated the stones and let him have the first move. He placed his black stone randomly on the board. It was clear. He did not know how to play.

"Haha, I was worried for nothing."
