It comes as a small annoyance and nothing more when he's tugged aside and told he'll be switching lab partners, which he meets only with a simple, mildly agitated voicing of, "But, I already have one..."
Side glances at Yamaguchi reveal that he's been shoved upon someone else, jittery and nervous and nearly knocking over test tubes—then opening his mouth to apologize and falling short (a "Sorry Tsukki" pushed back into the ribs of his throat). Tsukishima lingers long enough to watch Yamaguchi give a weak-hearted wave, then moves on—with a scowl twitching and tugging at the corners of his mouth—only to stop short.
He eyes Kuroo Tetsurou with the same, casual disdain he gives everyone else (a natural habit that comes too difficult to break, not like he'd bother to). Similar to every other encounter he's had with him, Kuroo adorns smirks and an easy slouch like a perennial headache (constantly pushing and forcing his way into Tsukishima's field of vision, and carving away at the worst possible nerve ending). He sighs, gives in, but doesn't bother to smooth the look of annoyance from his features.
