Summary
The usual warmth to Osomatsu’s dewy eyes is absent, frozen into narrow and pointy icicles that sink slightly under the creases traced on the skin directly below, his nose wrinkled with such distaste, it would have been cute if not for the gloomy ire he irradiates, especially when his lips contort into a disapproving frown. Cheeks puffed out, he taps his foot on the futon with incensed cadence, striking it as if to render it a simple mat. For a horribly long, agonizingly slow instant, Choromatsu feels his heart clench, until he realizes that Osomatsu’s sharp gaze isn’t stabbing at him, but somewhere lower. It’s a short moment of relief. As he looks down and finds himself staring dumbly into Nyaa-chan’s friendly smile, cold spills forth through his ribcage, his heart dropping steadily in temperature until it feels like it’s in his gut.
Or: Nyaa-chan is catching strays.
