#haivng a character than can smell specific things can tell us about other characters

Lingsha apparently only detects the smell of rain on Yanqing and that makes me wonder about the other potential meanings.

Why specifically rain? My thoughts go in all sorts of directions in terms of analysis and theory, thinking about his element of ice or where he'd have to be around to smell like rain of all things (or I'm just thinking too deeply into it haha, but there is a reason they put this sort of stuff here ToT). And it makes me think about Jing Yuan somewhat too since his element is lightning.

I need to hear more thoughts and speculations v-v
