So I've been reading a lot of Zhongli x Aether fics lately, and the development I see tends to split into two main camps, honestly. There's the post-archon-quest route, which is super popular. Writers love to mine that guilt and secrecy—Aether learning the truth and feeling betrayed, Zhongli grappling with the weight of his contract and the personal cost. It’s not just about forgiveness; it’s about rebuilding trust from a place of genuine hurt. They'll have these long, quiet conversations in Liyue Harbor or out by Nantianmen, where the dialogue does the heavy lifting. It’s a slow-burn through emotional labor, which can be really satisfying if you're into that sort of nuanced character study.
Then there's the other approach that just throws them into a completely different scenario—like a modern AU or a fantasy crossover—where their core essences are preserved but the baggage isn't. Suddenly you've got Professor Zhongli and exchange student Aether, and the relationship builds on shared curiosity and this ancient-being-meets-immortal-traveler dynamic without the Liyue plot hanging over them. The development feels more about discovery and mutual fascination, less about processing a specific betrayal. I find these often focus on the small, domestic moments that highlight their contrasting yet compatible personalities: Zhongli’s deliberate, knowledgeable pace versus Aether’s adaptable, experienced but weary perspective.
Personally, I lean towards the fics that remember Aether isn’t just a reactive character. The best ones give him his own agency—maybe he calls Zhongli out on his cryptic nonsense, or he’s the one initiating a new level of intimacy, turning the tables on the former archon. It flips the expected power dynamic in a really interesting way. A lot of writers also use physicality sparingly but effectively; a hand over his on a teacup, or a touch to the shoulder that lingers just a beat too long, carrying more meaning because of their shared history of unspoken things.
