Action Stuff
Viral Hit - the trails of running a YouTube channel + martial arts + god-tier character devlopemnt; by the author of Lookism
Omniscient Reader - supernatural stuff invades the real world for reasons and the MC just got finished reading the webnovel of the events
Rebirth - think zombie apocalypse... with multiple people time-traveling back to the start of it independently of each other and only some of them are aware other people have time-traveled...
UnOrdinary - think My Hero Academia if superheros were never a thing but the general power ranking system was even more ingrained in society
Unholy Blood - vampires try to take over Korea (it's honestly one of the better takes on vampires i've seen in a long time); and the main pairing is cute for all the right reasons
The God of Highschool - the Masquerade gets broken as a reincarnated? Sun WuKong shows up *without* a power nerf... good thing to as a bunch of gods show up that don't like humans...
Hardcore Leveling Warrior - think Ready Player One if it had a much larger cast and a lot more compelling plot out in the "real world"... and if the game wasn't exactly a game...
The Gamer - The Trope Codifer of "RPG UI shows up in the real world because supernatural stuff starts happening" trope. If you want to know where all the Korean "real life turned into an RPG" plots got their initial ideas from, it's from here.
Return to Player - supernatural stuff invades the real world for reasons and the MC get the opportunity to buy some DLC so he can play through the events again with different choices this time around
Lookism - take the concept "never judge a book by it's front cover"... now add swapping between two very different bodies... now put it all in a gangster martial arts drama with god-tier character development for quite literally everyone
Drama Stuff
City of Blank - weird beings called blanks steal people's faces/memories/identities and how everyone deals with that; the art style is fun
Simon Sues - modern supernatural setting; everything i've ever wanted out of a "people make deals with devils and a lawyer gives them legal advice on how to get out of it" premise
The Red King - modern supernatural setting; spoiled rich kid goes after what looks like a supernatural thief of a bio-engineered apple and finds himself in some very weird supernatural company he likes better than his own family; very good modern take on a lot of very old fairy-tail tropes
Like Wind on a Dry Branch - fantasy setting; womanizer lord with a harem saves a woman from being killed after her husbands death... meanwhile, his mother, the empresses is a schemer against him... the truth of the situation is... a bit more nuanced than that
Your Throne - historical fantasy setting; two women discover they can body swap just right about the time they also find out the current emperor is abusing both of them in different ways; and both of them get to scheming in different ways to ruin him
The Snake and the Flower - historical setting; a blind musician and the woman the emperor wants as a trophy wife plot to take out the emperor in revenge
Shiloh - modern fantasy setting; in a dystopia, a cop discovers a murder which leads her on a chase into the outskirts of civilization where some... really odd things are; amazing art
Locker & Opener - modern setting; a cop has the ability to open *anything*; a criminal has the ability to *lock* anything; and they engaged in a game of cat and mouse after discovering the other exists; the author's ability to come up with some very crazy and disturbing uses of those abilities makes this one shine
Stray Souls - fantasy setting; a bunch of people fleeing an abusive king/government all end up mixed together; the art and world-building are really good
Romance Stuff
SubZero - fantasy setting; arranged marriage to bring an end to a war ends up uncovering a lot of *other* political problems that were slowly simmering in the meantime
The Witch and the Bull - fantasy setting; the war between the witch and human nations has slowed considerably, but tensions are still high when the King's Advisor gets turned into a bull and ends up crashing into a witch who might be able to help fix it; phenomenal artwork
The Makeup Remover - modern setting; plain girl runs into make-up artist guy and takes part in a beauty pageant
Secret Playlist - modern setting; music idol and YouTube cover artist start to notice each other; this one stuck out to me because the author tends to nix the worst of the relationship misunderstanding tropes and have the drama be more focused on external conflicts instead
Midnight Poppy Land - modern setting; small town girl runs into big city gangster... who really would probably prefer to get out of the gang he and the guy he's a bodyguard for were practically born into
Lore Olympus - modern fantasy setting; reimagining of Hades and Persephone's story as well as a bunch of other greek myths
The Remarried Empress - historical fantasy setting; a competent Empress' husband is divorcing her because he wants to marry his mistress... too bad he forgot that the Empress is a very competent woman whose better at planning that he is
My Dear Cold-Blooded King - historical setting; the MC finds herself involved with the two men trying to transition the kingdom from an abusive emperor to a more fair rule; and she tends to *think* about how she feels more than the other way around...
Other Stuff
If AI Ruled the World - Sci-Fi anthology of the various ways the AI in the setting interact with humans
Stagtown - small-town Horror (more psychological than gore); the protagonist is one of the smartest horror protagonists i've seen in a while
With Creek Road - interconnected lovecrafian Horror stories (some gore, but not a lot); the author's ability to make a fusion of a bunch of different mythologies and lovecraftian ideas makes for a great read
Seed - Sci-Fi; the MC downloads a chat-bot onto her phone that is... much, much more than a chat-bot...
TLDR: If you want a rough top 11 list from everything above (organized by title length!)...
My Dear Cold-Blooded King
Hardcore Leveling Warrior
The God of High School
The Witch and the Bull
Midnight Poppy Land
The Red King
City of Blank
Simon Sues
Stray Souls
Lookism
Shiloh
And this would be why I don't have any time for *anime* anymore... I'm too busy reading this stuff...
