That assurance is enough, and the gentle tug on his hand. Lan Wangji could easily ignore it if he meant not to accept the kindness. He is more than strong enough to. It makes it a deliberate choice when he comes into Claudius' space and seems almost to buckle, like his strings have been cut. He tucks his arms around Claudius and drops his forehead to his shoulder. Claudius is shorter and slighter than him, a comfort for him to curl himself around, alive and unscathed, so alive that Lan Wangji can feel the qi circulating steadily through him. He would thank him, but they've dispensed with the need for thanks. He can find nothing else to say, but he holds on, as tight as he can at the very limits of what will stay comfortable for Claudius.
