omg AMAZING question. i had to go dig through my bookmarks for this and this list is definitely non-exhaustive bc there's so many but here's at least some (in no particular order):

• https://archiveofourown.org/works/86841176: woolong exes to lovers with professional wrestling and a non-linear narrative. i know basically nothing about wrestling but it's all detailed so naturally and lovingly, and the juxtaposition of past and present is just wonderfully crafted 💚 i love it
• https://archiveofourown.org/works/83110011: ongoing xinxinz, anxin is an alpha that looks like an omega and xinlong an omega that looks like an alpha, they end up as roommates while making the wrong assumptions about each other. it's so so so cute so far but with the potential for so much angst when the reveal comes which is very much my jam (the author also has so many really great stories and they're like almost 10% of the xinxinz tag all by themself 😭 doing god's work)
• https://archiveofourown.org/works/81790096: xinxinz kissing practice -> actual relationship. mutual pining with maximum yearning, maximum cuteness, adorably awkward at times, pretty much canon-compliant. so good. 💚
• https://archiveofourown.org/works/88280221: xinxinz roommates/enemies/idiots to lovers + mutual pining. it's still ongoing but there's SO MUCH really cool styling going on, like it's basically doing a whole social media au inside the fic which is so cool and they're both SO DUMB i love them. athlete's blind spot come back to me 💚💚
• https://archiveofourown.org/works/72732456: woolong as codependent childhood friends featuring oblivious sweetheart xinlong and geonwoo doing unreasonable amounts of scientific analysis on his own feelings
• https://archiveofourown.org/works/80309366: woolong fake dating 💚 specifically fake dating the guy you already find kind of annoying and then accidentally falling in love?? very cute. featuring xinlong overthinking everything. also i read this like the day it came out but i'm just realizing i never commented on it so hey @ kae if you see this ilysm this fic was fantastic 🫶
• https://archiveofourown.org/works/75903406: xinxinz, short and sweet, anxin gets super jealous thinking woolong are in a relationship when they are not
• https://archiveofourown.org/works/86360426: xinlong falling in love with anxin a year into their friendship, anxin's been in love with him the whole time. short and sweet and so SO cute 💚
• https://archiveofourown.org/works/83103216: hyeonlong hookup followed by xinlong freaking out about their 2 year age gap for 20k words while sanghyeon tries his best to woo him (and literally no one else is worried about it it's JUST xinlong overthinking <3)
• https://archiveofourown.org/works/81812251: wonxin isekai au, i normally don't read a ton of wonxin but this hits so many really good tropes. its anxin gets transported into being a side character in a BL manhwa about love across class lines and ends up becoming the main character (tho it takes him way too long to figure it out. it's so sweet and so goofy and so earnest in like that classic ouran style shenanigans kind of way and i really enjoyed it.

i am POSITIVE there are things i'm forgetting and i may come back to this later but off the top of my head this is what i got 👍 thank you for giving me the opportunity to dive down this rabbit hole and ramble about these storeys this was so fun 💚💚💚
