"Nishi, why the hell are you singing in the bathroom at 5AM??"
"I'm happy!" Nishijima yells. He spits in the basin, shuts off the water, and swaydances his way back down the hall, swinging his towel around his head. "I JUST WANNA GET A KI-II-II-II-II-SSSS..!!"
He tries to field the pillow, but it still hits him in the face. Through it, he asks, "Breakfast now or later, then?"
Nishijima leaves the door open, and, as he turns, still humming, he pauses. The slightly muffled sound of Hidaka harmonizing with him floats out. Hidaka makes him happy.
