Even Lan Wangji is tearing up a little watching this, because he does want to tell Wei Ying: he's more than healthy, he's more than happy. He's one of the most well-adjusted, sensible young men I know. He's better than either of us were at his age, he wants to say. I'm so proud of him sits at the tip of his tongue.

He says, instead, "Wei Ying, you would be proud of him." And that's essentially the same thing, anyway.

He knows he has much else he needs to tell Wei Ying, but that can wait for another time. He is selfishly enjoying this moment, this perfect moment that he can treasure, for which everything else can wait its turn.

This is possibly the first time that he'd arrived here, that he feels truly calm. And honestly, he can selfishly hold onto that a bit longer, too.
