i've been postponing answering this questions because i wanted to collect my thoughts ahah
hii <3
so...where do i even start. ofc his overall story has me in clutches, i love medieval fantasy and i love the rich history of mondstadt where his presence is everywhere in small events that you have to read through and catch by yourself. the first time we see him in game is also great - it's not in deadly tension as in case with raiden who you pretty much ready to fight and not in a "let's work together while i'm kinda lying to you" with morax (no shade) but rather you get to see venti's serious, real side where it's nobody else around. it contrasts perfectly with his gentle side, he's like a classic jester type in media where you know he can and will prank you but instead of proving that by doing anything direct and harmful you get this from stories about his "misdeeds". instead he showers you with soothing words and caring actions. i also like the fact that he cares the most - people misread him as lazy and avoiding but he's literally the guy trying to solve the problem all alone when we start his archon quest. we get to see his actions being deeply integrated in monds culture as well - he singlehandedly controls terrain structure and climate in mond, making sure his people still have everything they need for comfort living; i love how he devotes himself to helping heroes of each grand trial of new era for mond and never acknowledges himself as an acting figure. i also love how insanely smart he is still behind all that air of foolery, as he is preserving important historical events from irmunsul with making them into folklore (BP narrative included). there was also a thing that got him badmouthed in the fandom after first windblume with barbara situation but i found all his choices being purely logical while still maintaining safety for his people. if you don't remember what i'm talking abt i can elaborate ahfhf. like a pure bard he also possesses insane charisma that lets him befriend literally anything and anyone, dragons and witches and even stars

i love how humane he feels while not being human as well - he cares about us and our happiness in a godly, protecting way, but then you get to see him genuinely melancholic and upset about missing his old dead friends and you just wanna protect him in return :( it gets deeper once you realize that our bond with him is truly special - we've met him even before we think we've met him, he cared about us while we were sleeping (not 100% confirmed yet but i'm never wrong), he names some locations in mond in our honour and he constantly seeks us out alone, going so far as to ask us to leave paimon behind..needy much huh
aaand ofc i love his design, whites and blacks and teals are my favourite colours in character designs and he can look both goofy and cute and absolutely holy the next second. his eyes are the colour of the sky- i should stop jhfg.
there's much more that i love abt him but this is already the size of a small essay. thank you for the question tho ;u; i rarely get to share my love like this

OH NO I MISSED THIS QUESTION IM SORRY ANON i haven't read anything long for these two in a while actually but i can recommend some stuff that i still remember :D

MY ABSOLUTE FAV it's so simply amazing i adore scam email jokes and this is the joke that evolves into something that gave me serotonin. short: rich boy diluc gets scam email from khaenri'ah prince

omg hi,, thank you very much hehe ДЯКУЮ
i have some aeventi stories that will never see the light of day...let me think hmm
1. i already commissioned this once but i really like them being very domestic and lovey-dovey inside aether's teapot. venti growing grapes for wine there. venti just chilling around the house playing for him or them swimming in the artificial sea. the summer vibe of it all ahh
2. mond festival traditions - aether is picked to be a ludi harpastum lady (even tho he isn't it's still cute) and he has to throw ludi harpastum for everyone to catch. venti ofc is a champion at this game and cheats easily to get his kiss. they dance in flowers for everyone to see
3. post-endgame, mond is left w/o it's god bc venti gone into the abyss to retrieve souls of those who got trapped there after death. couple of years passes in which aether stays in mond to help rebuild it after the destruction, there are posts everywhere on the borders to help finding still missing people. finally after all this time someone from the city feels the wind? venti is back with kaeya in tow, as he was the last soul venti bringed back from the war. there is no windless land no more and venti w/o his gnosis has no powers left after saving all lost souls collapses at one of the posts just to see his city for the last time. ofc aether manages to save him just in time and pours half of his now godly powers into venti, leaving himself w/o enough energy to leave teyvat ever. while venti is mortified aether is happy even tho he and lumine are stuck there forever (yeah i think of this one a lot)
4. khaenri'ah royalty twins and celestia rulers meet for negotiations of who will rule over mortals? having the queen piece venti has to be on every meeting and fool/please the twins to give up. eventually their enemies-to-crushenemies flirting brings venti to the point where he wished for lumine and aether to win the war against celestia. every other celestia ruler (archons) is very judgemental lmao
5. venti shows aether closed off old lands of mond with the statues of first gods. he wants aether to meet istaroth and old gods and spirits possess them for a moment and to fullfill some old ritual and please those gods they get a bit spicy at the altar
6. literally anything...aeven is so precious to me and there is so little content to read i'm happy to see any story that doesn't k*ll off one of them or has some dead dove levels of possessiveness idk. wish i knew how to write at all
