Lan Wangji looks at him stoically. He was kind. He need some space and distance to heal properly. Perhaps the words and promise they shared not too long ago becomes a distant dream, an ideal. The truth of it is he now knows that he belongs to the other man, rightfully so, and his emotions, he tries to keep it contained with self-restraint, knowing it's proper and the right thing to feel.

Or perhaps, he was moved by his Wei Ying's devotion and loyalty to him, that he is willing to follow him to the nothingness of death and beyond.

"I know that's unnecessary, and I don't want to loose anything between us. Your friendship means a lot to me, Wei Ying. And we still are. My death is...it was an accident." He said, voice hollow, but knowing he felt better by giving voice to what weight heavily on his thoughts, incoherent and uncertain to how that felt to him.
