(fan work of haikyuu) He wasn't sad at all.

(The Italic words are Unnan Keisuke's thoughts.)

Unnan was seated on one of the chairs along the corridor, usually apathetic expression across his face, tired-looking dark eyes downturned, his bag loosely resting on his back, his thoughts packing his mind.

I didn't and will never feel sorry for someone full of foolishness whose blocks was often fewer than me. I couldn't tolerate his stupid arguments that he seemed to find witty. However, now I feel it not so bad to have an idiot to tease, who was always easy to be irritated and frequently responded my taunts with force. Although he clamped my face out of shape in his hand, I grabbed his hair in return, which truly made some funny memories. It seemed to bring me some pleasure when having him around, to be honest.

Unnan could never understand such a feverish fan who carried a newly bought photo album of his idol, looking at it even when crossing the road. He recalled that his stupid teammate was clasping the album tightly when falling to the ground, while Unnan was just too petrified to leap into any action.

"Are you OK, Keisuke-san?" Usuri's voice got Unnan out of his mind. With this, Unnan tilted his head up a little to lay his glassy eyes on the familiar big round eyes. "Nothing much, I think. I am just tired." He suddenly wanted to say something else to Usuri, but stopped here instead. Usuri didn't see much emotion in his eyes, but he looked a little weighed down by something.

I suggest you spend as much time as possible with Kiryuu, because it seems that he will be very busy soon. Although he tends to over-analyze, he is actually obtuse in this aspect. You are sure to know which aspect I am referring to.
