7 Novel Recommendations (VERY long post)
If you like Trapped in a Webnovel, you might also like the following (click to expand).
WARNING : spoilers ahead, though I tried making them vague
Warning 2: these are all NOVELS. Unless otherwise stated, they have no comic adaptations. Only no. 4 & 5 have manhwa versions so far.

Still here? Ok, let’s proceed.
*Bromance ratings provided in units of Jonghyuk, where 0=no bait, 1=are you sure this is not BL

1-“The Editor is the Novel’s Extra”
(Do NOT confuse this with “The Novel’s Extra,” these are different novels! TNE is a harem, EITNE is not)
An editor is transported into the world of a 8-times rewritten manuscript & possesses Kleio, the timid son of a nobleman. He doesn’t want to get involved, but his talent in magic puts him in the role of the kingmaker (Merlin-type character backing the original MC, the 3rd prince who is literally named Arthur).
Cons: Really slow at the beginning. If you like the protagonist to jump into action right away, don’t read this.
Pros: Wait for political schemes, & a villain who is genuinely a threat. Arthur’s older brother Melchior is politically smart & uses charisma to manipulate people - though he’s not blindly evil.
Also, the psychological aspect is really good. Kleio might be an editor, so he’s fine with saying “this world is fictional,” but a few other characters (not transmigrators, as in 2-3 characters born in the manuscript so far) become aware of the drafts being rewritten. Author (unlike most other writers of this mini-genre) actually explores mental instability/irrational grudges being fueled by having conflicting sets of memories each time the author rewrites the draft.
Bromance Level: 0.3 Jonghyuk

2-S-Classes That I Raised
In which our MC, Yoojin (F-class) resents his S-class hunter little brother, but after his younger brother dies saving him, he regrets everything & wishes to go back in time. When time resets, he find that he now has the skill “Perfect Caregiver,” with which he can “raise” people with talent. First half is a wacky comedy in which he manages a bunch of yandere-ish S-class hunters who all like him, but don’t necessarily like each other. Second half takes a sharp turn for the serious, going into the nitty-gritty of timelines & paradoxes (still a comedy though).
Cons: confusing if you skim instead of read. Also, anti-JP sentiment typical of KR novels, but you can skip these bits.
Pros: dynamics between characters. It might look all fluffy, “MC beloved by everyone,” but it isn’t entirely. A few of the S-classes have twisted ideas of family, putting MC in physical danger, which prevents him from being too OP. Also, our MC Yoojin’s dynamic with his little brother goes between “haha both of them are yanderes” & “damn-onion cutting ninjas really going at it with the inferiority complex VS unresolved guilt.” And it works better than it sounds.
Bromance: 0.7 Jonghyuk

3-Legend of the Sun Knight
Not a dungeon or transmigrator story, but a pure fantasy/action. It’s a comedy in which our main cast, who all are high-ranking knights working for the church, have to act out pre-set roles that contradict their personalities. The titular Sun Knight, our vicious MC, has to pretend to be an all-loving hero while dealing with scandals in the palace, taxation issues, revolts, demons, etc.
Cons: lots of info dumping
Pros: a bromance level of 0.5 Jonghyuk

4-Omniscient Reader (novel & comic both)
Do I really have to introduce this one? This is the king of epic Korean bromance. Please do read the novel too, as there are some metal quotes & beautiful turns of phrase that got cut out of the comic adaptation. Search up “ORV Boxnovel” to access all 551 novel chapters.
Bromance: 1.0 Jonghyuk
because this is literally where Jonghyuk (aka. The 1st to say “2 men can be Companions of Life and Death, and live 1000 lifetimes to meet again, but no homo”) comes from

5-Trash of the Count’s Family (novel & comic both)
Smart protagonist who claims he is lazy, but is revealed to be a super unreliable narrator, with a huge-scale plot involving naval battles (Operation Ghost arc is fantastic), politics, etc. So much foreshadowing. Heck, even what people complain about (how come MC isn’t trying to go back? Why’s he so calm & seems used to this?) are later explained (hohoho, TCF chapter 273) & become plot points (around the 500-600 ch. marks). Go on Eat Apple Pies to read.
Bromance: 0.6 Jonghyuk. It was 0.4 in the beginning, but Postype has a ton of ChoiCale fanfic

Now, for the recommendations that I hesitate to give you…

6-Regressor Instruction Manual
A bunch of people from Earth wake up in a monster-infested dungeon. Our MC, Kiyoung, is actually a man w/ no sword/magic talent. However, he can see the titles of others (like a game stat board). He realizes that one of the other people—Kim Hyunsung—is a regressor & latches onto the regressor (plus a bunch of other people w/ potential) in order to survive. Kiyoung quickly realizes that while these people are better at fighting, he’s the one who best understands politics & how to deal with rival guilds.
Cons: the harem. Some of the female characters are well-written, some are… not. Also, the MC really is scummy.
Pros: MC is not just a bastard, he is a Magnificent Bastard. Fun to watch his schemes succeed, fun to watch him also trip himself up when his plans don’t go right.
Also, BROMANCE. There’s the princess carry scene, the part where only the MC can snap the regressor out of a breakdown, the part where the ML falls in love with the MC’s genderbent form (long story), ML imprisoning MC in a windowless room to “protect him from the world,” etc. If you thought I was exaggerating, too bad; all of these things happened. Come get y’all gaybaiting juice.
Bromance: 0.8 Jonghyuk

7-I Don’t Want This Reincarnation
An ACTUAL BL novel in a dungeon setting. MC is a man who wakes up in the body of a really unfortunate fictional character who works as the henchman of the main villain. Somehow, he gains the attention of both the villain & hero.
Cons: Novel just started being translated.
Pros: Go to Novel Updates & look this up. No, really, do it. The MC Yigyeol looks identical to Choi Yuseong, but with slightly darker hair (think sand blonde instead of champagne blonde). Both of the MLs look like Dojin. The villain looks like Dojin (behavior: sadistic edition) with long bangs. Hero looks like Dojin (behavior: cold edition, with hidden yandere) with his hair parted on the other side. If you want to see a MC who looks just like Yuseong collect a harem of Dojin expies, read this. Also, the plot is fun & there’s a lot of action (not the R-rated kind, this isn’t explicit in that way. I mean battle scenes)
Bromance: This is straight-up BL. Do not measure with Jonghyuks.

Now, as for where to read:
Type “novel name” + “Novel Updates” into Google search bar. Exceptions are Trash Count (b/c the Korean fandom found out about translations) & Omniscient Reader (NU page only has chapters till 39), so for either of these, you’ll have to find an aggregator site.
