Lan Zhan, what did he just say about springing romantic notions like this on him?

He wants to bury his face against Lan Zhan's chest, but he is too transfixed to move. His heart feels too big for him, radiant, overwhelming, and he does not know what to do with any of it. Will it wink out if he looks away? He does not dare.

And still Lan Zhan sings.

zhǔ yī hú shēng sǐ bēi huān jì shào nián láng
míng yuè yī jiù hé lái chàng wǎng...

(Teach these young ones life and death’s joy and grief
As constant as the bright moon waxes and wanes...)
