The early part of this webtoon followed a trend 12 years ago, so the early part might not suit your taste, but since then it has been the best love webtoon I've ever seen. It actually ranked first or second in the Korean webtoon market for 10 years. For your information, only 86 chapters have been translated into English, but it actually has up to 442 chapters.

Actually, the very first episodes were hazy for me because it's been ages since I started reading this manhwa, but I sure am this one is the best romcom manhwa I've ever read! It really is a work of art. I can literally type a whole essay babbling about how I cherish LR so damn much. The amount of memes implied in the convos truly is my favorite part as a comedy genre lover HAHAHA. Also, its not only focusing on our main couple, so you won't get bored easily! Nevertheless, Gongju (MC) 's behavior in the first episodes was really annoying LOL, I it, but he gets all the character development all throughout the stories, and so's all the cast too. The best character development, indeed, definitely deserves a 10 out of 10.

very hilarius and funny and have cute romance. all characters are lovable.

I am 20 chapters in and so far this has been nothing but the most bitchmade annoying loser ML I've ever seen and a cast of unlikable gremlins trying to browbeat the FL into dating a guy that she has zero interest in. Maybe the previous review is right and it gets better later on but 46 chapters of the most insufferable characters ever doing meme faces at each other is a lot to ask for on the off chance the MC stops being a creep.

PLEASE READ MY REVIEW TO THE END.
Love revolution starts with a high-school themed romance comedy drama. The webtoon has a very kdrama-ish style writing of conversation and jokes, you might enjoy reading it a lot if you're used to korean cultures or have watched some kdramas.
This webtoon has a very boring development at the start which is why tons of people dropped it so fast and ended up giving bad rating.
So i BEG you, to push yourself to read it at least until chap 46, because that's where MC & FMC romance development started progressively.
If you've read Kanojo okarishimasu, this MC has similar development to that but the difference is he's handsome, good at singing, cooking, dancing, he's rich, he can be a chad if he want to, and most importantly he's not a goddmn japanese perverted beta. He is also very loyal to FMC until today, but he's not 100% submissive to her (he fought back a lot, actually).
The MC will get you irritated at some points, but at the end of every conflicts he will always be the best gentleman and make everything going back to place. Along with the story, the MC will come to fully understand the FMC and get over his idiotic behavior meanwhile the FMC will get used to him and fall for him at the middle chapters (actually faster than you think) and their relationship will have so many wholesome moments that will make your heart flutter and suddenly want to restart high school again.
For the one who's confused about where is this story going, keep reading it to season 3 (chap 297), because that's where the REAL SHT begins. His friends' will reveal their shades and suddenly this webtoon turns from a slice of life comedy romance to an intense drama series that will make you anxious everytime you read new chapters. The conflict is very complex, and some side characters became so annoying that in this last season, you will start to appreciate the MC more and ironically he'll be the most likable character.
NTR? Nope. The FMC is an ice queen and not easy to open her heart to a guy (that's why the MC tried so hard to get her), but soon she'll be the one to become head over heels for MC. And don't even think of a shitty ending since the author did a very good job of writing.
FYI, for the current conflict, the MC has gotten enough sht of FMC. You know where this is going ;-).
Last words, this is one of the best romance comic i've ever read with the best character development.
