Wei Ying's voice cracks and he sounds so upset - he looks so upset, that Lan Wangji winces involuntarily. Had he been so untoward? Is Wei Ying so revulsed by him? He runs away, and Lan Wangji feels like he'd been struck in the face by him. He isn't sure if he will make it worse by running after him, but he must. He can't leave this undone, unsettled. He feels hot all over, and panicked, and he can't breathe, and that his heart has fallen out of his chest.

Against his better judgement - or with no judgement cals made, he runs after Wei Ying, though that boy is fast and he's out of spiritual power. Not that it'd give him the upper hand, as Wei Ying wasn't lacking in any himself.

"Please, Wei Ying!" he yells after him, his voice uncharacteristically strained. What has he done? What has he and his fool heart and stupid mind done, to lose Wei Ying like this? He can't breathe, and his heart is beating too fast, and his vision seems to swim. He feels like he's drowning, and he keeps swimming up towards a hand that's just out of reach. "Stop --!"
