Uhhhm so! It's all tropes i enjoy in the alnst/ivantill fandom specifically because i've never read so many fics as i have for them lol
I really like the fake dating trope tbh, and it makes me sad there aren't really many ivantill fics with this 😔
Then mhhhm i'm a huge fan of hanahaki aus for the pure angst potential of them, though i often find myself not liking the endings because they can feel too cheap- my fav fics for it are "love blooms" by kate882 and "whether you like it or not" by hot_island_songs (not complete yet but it's soooo good i swear). I'm also super excited for nemo's upcoming post hanahaki surgery fic heheh
Then! I'm also a fan of time travel/time loops. I've read such incredible fics for it... "anaphora" by zombiekittiez is one of my all time favorites (though mind it's pretty dark) and "dividing by zero" by quillifer is also incredible
Also also also i have a huge soft spot for sickfics! Here i obviously recommend "idiots can't catch colds" by my dear pinecow and also "talking, but i'm tongue-tied" by littencloud9 (which also features jealous Till which i adore)
Then i obviously also love actor aus as a consequence of alnst's otr ofc,, and i'm the biggest hurt/comfort enjoyer too
This turned into a fic recs type of reply 😭 but i truly love yapping about fics i love so you should check all of these out, they're great
