Growing up I loved reading those stories on webtoon where each chapter or every few chapters would feature a new story. I spent a lot of time reading these and now Im trying to find these but in film form!! Ive already watched goedam, and im highly anticipating season 2!! Does anyone have any recommendations?

76 Horror Bookstore
Persona
Girl from Nowhere - this follows the same girl but each episode is its own story, unrelated to the previous one
AI, Her  - this one is.a little tricky. It was sadly cancelled in the middle due to Covid and it being filmed in Spain but the 3 episodes that are done are amazing and tell of a very interesting story. Interlinked but not per say connected.

Also what I'd recommend you is to try the Drama Stage and Drama Special movies. They are very short movies (mostly just 50min long) that are done by new screenwriters and are always quite unique. Some I'd recommend you there are:
Drama Stage Season 3: Everyone is There
Drama Stage Season 3: My uncle is Audrey Hepburn (this one is less thriller/horror related, but its quite good)
Drama Stage Season 3: Blackout
Drama Stage Season 4: The Fair

I absolutely love horror anthologies! Both in the written form and on screen. Here are some of my favorites from Asia:

Tales of the Unusual (2000)

Three... Extremes (2004)

Dark Tales of Japan (2004)

Dead Stock (2017) - MyDramaList 

The Grotesque Mansion (2021)

Midnight Horror: Six Nights (2022)

I haven't watched this one yet but it is on my plan to watch list: 

Zoo (2005) - MyDramaList 

There are also a couple of Japanese directors that did episodes of Masters of Horror (TV Series 2005–2007). Really I encourage you to watch all of Masters of Horror if you haven't yet, that's one of my favorite anthology series of all time. I go back and rewatch my favorite episodes from it every few years.  I  can give you more recommendations outside of Asia too if you would like, I've watched a ton of them.
