mmh that's a very good question because i read on pairings i am obsessed with i can read a lot of stuff without preferences and like if in my mind some ships fit more some trope i'll look for those even if they're not "my favs"
if i had to chose i'll say my favs trope are everything college/university and i have a thing for friends to lovers.. (i used to be a big enemies to lovers fan but not anymore), i adore a good soulmate au think it never gets old and everything found family. I enjoy friendships and bounds that go farther than just the romantic relationship, but once again i'd read anything except pure angst on my favorite ship
if i read on animé fandom i love canon compliant but not much in kpop

i think it is different when i write because i enjoy writing fantasy and world building stuff but tbh i will not read much of it otherwise... but those stuff (except for a blooming spell) are fics i haven't published. If you check my ao3 i think you'll find fics that i'd have read (hogwarts au i love reading/writing, strangers to lovers and falling in love, getting together fics), i don't think i do much psychology/character study, but nostalgia is a theme very intense in my writing and i don't really read on it tbh because i don't want to be too sad when i read

thank you for all your very cool questions:)

hey hey!! i had a good day thank you i hope you did too!

ofc my top fav pairing changes all the time it truly depends on my current obsessive mood but these days it is def sevngj!n and i think it'll still forever be in the top of my fav ships (tbh back when i wrote my first sevngj!n fic i was not even a fan of the group just my best friend was a stay and i ended up being obsessed with a ship i was not supposed to stan??) because it's just.. so adorable their dynamic gives me immediately so much inspiration and thoughts and like also makes me wanna curl myself into a ball and cry (happily), like we talked about once i really enjoy this kind of dynamic with very love expressive one and more reserved other, it just fits perfectly!
i enjoy other s k z ship but for my favs favs i have to mention in t b z m!lc0b just like sevngj!n i find a lot of comfort in that ship and when i first started to stan the group it caught my eyes immediately because of a video in which hyvnjae says he is the devil and jac0b is an angel. i just love the way hyvnjae cares a lot and like it's in his eyes most of the time, it's just so adorable
(i also adore svnkyu ship)
just to mention one last ship i'll say in iz*0ne there is the m!nju/yuj!n (now !ve member) that i cherish so much... and i'll be putting them in my fics when i can
