hey sure!! remember these are just my opinions & experiences everyone

well for starters: cyno/tighnari
i loveeee cyno, loved him way before sumeru came out and even before inazuma, i think as early as 1.5? however i don't really gaf about tighnari lol usually i'd just be neutral on such ships but the blatant mischaracterization, racism and ignore within this ship's fandom back during the sumeru patches turned me off really badly. i also just don't find their dynamic particularly interesting and it doesn't suit my tastes. but yes, the racist shit etc is the thing that made me actively hate it!! now im not gonna block someone for shipping it or anything i just do not fuck with it

for tartaglia/lumine the answer is simply: not very interested in the ship, do not care all that much for childe ships, and i play as aether so the ship is kind of lost on me? the latter one sounds perhaps more like an excuse as i do indulge in lumine x ayaka but in those cases i often also ship aether with the character and i just. don't really care at all about the childe x traveler relationship (romantically) dunno

no hate to the chilumi shippers tho they got insane fanart from what i see occasionally and i do rt it occasionally but it's just. not my tea

re: itto ships
the one with gorou? hate it and anyone who was here during inz patches knows exactly why
the one with sara? ive softened up for one moot (& out of spite) but just don't care for it at all so i dont engage with the ship content
itto is like. a very unshippable character to me and i hate what hoyo has done with him since sq itto and event itto are very very different people imho

i think that covers everything?
