It's one of those reincarnation, transmigrated villainess webtoon.
I can't remember the exact details but I think MC transmigrated to a Villainess' body. The Villainess is not actually a villain, she basically just pretends like she did all these evil deeds (that someone else was doing) because she was too wimpy and was getting manipulated into taking the blame. OGfl was the woman that her crush liked and was claimed to be bullied by the OG villainess BUT OGvillainess was actually friends with OGfl and that's why OGfl refused to press any charges against the OGvillainess. I think OGfl disappeared at this point in the story.

It’s about this guy who was chosen to go through this place that basically gives you different trials. His first trial was so try an escape a room. I think the room had a window with steel bars and there was also a huge rock lodge in the wall. He tried to move the rock but it was too heavy, so plan B was to saw off the steel bars I think. Eventually, he realizes that the rock was actually a turtle’s back so I think he used heat to make the turtle move. There was also another trial whereii he was placed at the bottom of a pit and was given an egg as a way to escape. He raised that egg, used the feathers to fly out of there. Does anyone have a clue which webtoon this is?

I don't remember much, but it's basically about this girl, who is always alone in the library. She is a bit timid and one of the boys in her class harshly criticized her for it; from that day on she's been scared of that boy. The library is basically her refuge, and one day, she found a letter in one of the books, she ended up writing a reply to the letter and tucking it in the book. Surprisingly, she got a reply to it o.o and that's how their correspondence started. If I'm not mistaken, she thought that she was corresponding with this gentle boy that she liked, but it turned out it was the boy that she found scary. He was a tsun2x I think and in reality had a crush on the girl hahah. I remember a scene where the boy was playing soccer (?), and he would always see the girl by the library window. I think he maybe liked the way her expressions changed while she was reading the book (?).
Sorry for the fuzzy memory XD

I think this is it

The setting is basically in a world where humans have become rare, and like 90% of the population are demons (they look like humans but they just have horns that is normally concealed). It's a highschool type of setting as well.
The seme was in heat (?) so his horns were out and he was passed out in some random corner. The unassuming uke (human) was passing by and helped him to go to the clinic. The seme noted that the uke smelled good/delicious. Anyway, while the seme was passed out the uke touched his horns and apparently that's like touching a boob. Fast forward in the classroom, the seme still had his horns out and girls were going gaga over him, and while the uke walked passed him, he remembered the uke's smell and basically yetted the uke out to the rooftop (?) so they could talk. The seme was like, "why did you touch my horns?", but that was basically just an excuse, cause he really just wanted to taste the uke, which he did.

This is set in ancient Korea
It's about an extremely lustful and sexy seme (gosh he's sexy o.o) who is known for his debauchery in Korean high society. He is looking for an erotica painter (the uke) because he is fascinated (and turned on) by the uke's paintings. Anyways, he finds the unassuming uke wasted in a restaurant. He lurches at the uke and gushes about how much he loves his work, but the uke denies being the painter. The seme, out of nowhere kills his servant for getting the wrong person.
The uke, scared and still partially drunk: faints. When he woke up, the seme had him in his mansion, who is now fully aware that uke IS the painter because he found the uke's painting tools. The uke cries, and told the seme that he quit already; but the seme is persistent. He ended up forcing the uke to watch him have sex with a sex friend (?), so he could paint them, but the uke was just confused and blushing the whole time so could not paint them.
I remember the seme is very straightforward and selfish with his actions, but he's gentle with the uke and even gives him head pats.
I remember that the art was extremely beautiful, and this was a recent update, I thought I had it saved but I guess I didn't T_T

It's about twin sisters.
They both like the same guy; the guy is going out with the outgoing twin (Twin A). Twin A and the guy are about to get married, but the guy got in an accident where he lost his eyesight while trying to save Twin B. Twin A ended up ending her marriage with the guy, because she was not confident enough that she can support him throughout this whole ordeal. Twin B ended up supporting the guy, while pretending she was Twin A. The guy eventually got his eyesight back, and he planned to continue his marriage preparations with Twin A (who is actually Twin B) who he thought was supporting him this whole time. Twin B gave way and allowed Twin A to come back into the scene and marry the guy, but at the marriage ceremony, the guy felt something was off.

I actually asked this question myself and I'm so happy I can help!

It's about 2 friends.
One is an innocent, no nonsense seme, and the other is a handsome and carefree (frivolous?) uke.
Anyways, they're bestfriends. The uke has always had a crush on the seme, but seme is absolutely clueless, and is crushing on a senpai instead. Seme always kind of gushes about his crush to the uke, and the uke pretends to be lighthearted about it. Oneday, the seme finds out about uke's feeelings, he felt kind of trouble by it at first, but he realized that he also has had feelings for the uke.
I only remember the scene where they had their first moochpooch, and the uke was like "don't underestimate a virgin with a big dick" lol while absolutely in tears.
Hahahah!

It's about this seme who is a king (I believe), he has an uke who he takes in. They are basically lovers. Anyways, the king always gives sugar cubes to the uke, to which the uke always keeps. Anyways, the king becomes powerful, and he takes in other concubines, and forgets about the uke. The uke is really sad about this, something happens, and in the end, the king realize that the reason he wanted to be powerful in the first place, was for the uke's sake.
Hi gogoers,
I’m looking for recommendations where the FL is isekai’d to a different body and ML used to dislike the OG Fl so therefore he may be a little mean/looks down on the actual FL.
I know it sounds like a typical plot, but often times, I see alot of plot that are kinda like this but then it turns out that either: a. ML turns out to have liked the OG Fl all along, b. the mean “ML” turns out to not be the ML after all, c. ML has no personality. I don’t like these plot twists >: (
Please recommend me good ones. Thanks all <3
I forgot to mention if someone could specifically also recommend more modern setting (in that case, it wouldn’t really be isekai but more of body switch :’)). Historical setting isekai also welcome. Thanks!
Sorry I don't like modern ones, so I can give you only isekai ( ̄∇ ̄")

Totally unrelated but this is the first seeing someone actually call users here "goers"like that's genuinely funny.
Thank you <3
Hahah, aren’t we exactly that though? XD
