15 Novels

Korean romance with ruthless protagonists pairs calculated behavior with emotional vulnerability. These MCs approach life pragmatically, whether navigating fantasy power systems or corporate hierarchies, but romance disrupts their control. The tension between ruthless efficiency and genuine feeling drives these narratives.

Ruthless protagonists in romance create higher stakes for emotional moments. When a character who never shows weakness reveals genuine affection, it carries more weight. Many feature regressors or reincarnated characters with hidden agendas, adding layers to their romantic involvement.

Kidnapped Dragons
4.6
(1.2K ratings)
Genre: action, drama, fantasy
– The planet [Earth] has entered the abnormal state [Apocalypse]. – You have failed in saving the Earth.
First Impressions
"Kidnapped Dragons" is a web novel that really took me by surprise. With its blend of action, drama, fantasy, and even slice-of-life elements, it's a story that's hard to pin down, but ultimately rewarding. The premise itself – a regressor MC who has failed to save the world six times, now tasked with caring for young dragons – felt intriguing enough to draw me in. Initially, I was a little wary. The sheer number of tags (over 60!) made me wonder if it would be a case of too many ideas vying for attention. And, admittedly, the early chapters might not grab everyone immediately. Some readers fo...

You’ve Got The Wrong House, Villain
4.3
(982 ratings)
Genre: action, fantasy, josei
As if it wasn’t enough for me to be reincarnated as a child in the slums, I was taken to a city of crime and became a test subject. But then, when I saw the man that came to destroy the research institute, I realized that this was the world of an angst-filled reverse harem novel.
First Impressions
"You've Got The Wrong House, Villain" had me intrigued from the start with its unique premise. It blends familiar tropes of reincarnation and reverse harems with a dash of sci-fi and psychological elements, which is quite the combination! While it's not without its flaws, there's definitely something captivating about this story that kept me reading. Initially, I was drawn in by the MC, Yuri. The idea of a cool, level-headed woman with superpowers, navigating a world she knows from a novel, seemed promising. The early chapters set a good pace, introducing the core characters and hinting at the...

HIGHLY RECOMMENDED
The Regressed Demon Lord is Kind
4.3
(703 ratings)
Genre: action, adventure, comedy
My whole life, all I wanted was power. I churned the world into rivers of blood and eventually gained the title, ‘Demon Lord of Strength’.
First Impressions
"The Regressed Demon Lord is Kind" is a web novel that certainly took me for a ride. Going in, I wasn't quite sure what to expect, but I came away with a generally positive impression, though not without a few reservations. Initially, the premise felt somewhat familiar: a regressed protagonist aiming to live a kinder life. However, it quickly became apparent that the author was playing with expectations. The "kindness" in the title should probably be in quotes, as the main character, Zich, has a rather... unique interpretation of the concept. It’s more about beating up bad guys in the name of ...

I Became A Flashing Genius At The Magic Academy
4.1
(534 ratings)
Genre: action, adventure, fantasy
A character with extreme difficulty and the worst performance, Baek Yu-Seol was considered tr*sh in the game because he couldn’t use magic in a fantasy world where everyone else could. However… Suddenly, those words echoed in my mind before I was transmigrated to the Aether World.
First Impressions
"I Became A Flashing Genius At The Magic Academy" certainly grabbed my attention with its blend of action, adventure, and school life elements. The premise of a protagonist mastering a seemingly useless "blink" spell in a magic academy sounded like a recipe for some clever and exciting scenarios. After diving in, I can see why it has a dedicated fanbase, but also where it falls short. The initial chapters are undeniably captivating. I was immediately drawn in by the unique game-like world and the main character's seemingly underpowered ability. The story does a great job of establishing the se...

EDITORS CHOICE
The Man’s Perfect Wife
4.3
(541 ratings)
Genre: action, adult, drama
The foundation of South Korea’s high society is money, power, and marriage. His marriage was considered a mere ‘contract’ between the fathers.
First Impressions
"The Man's Perfect Wife" is a whirlwind of passion, drama, and secrets. I dove in expecting a typical arranged marriage trope, but I was quickly proven wrong. This story grabs you from the prologue and doesn't let go until the epilogue. Initially, I was drawn in by the promise of some steamy scenes, and I wasn’t disappointed. The summary hints at a marriage of convenience between Min Yuan and Seo JoonHun, seemingly destined to fall apart. However, the author quickly subverts expectations, revealing a much darker and more complex plot involving family secrets and revenge. The initial chapters a...

The Baby Raising A Devil
4.4
(409 ratings)
Genre: adventure, comedy, fantasy
Three regressions, 4th life. Although she was prophesied and raised as the child of fate, she was sacrificed when the real child of fate appears.
First Impressions
"The Baby Raising A Devil" had me hooked from the get-go with its intriguing premise. A multi-reincarnated protagonist, a loving family, and a dash of villainy? Count me in! I've dived into the available chapters, and here are my thoughts. Initially, the translation quality was a hurdle. I saw some readers mention this, and I agree that some of the earlier chapters felt a bit rough around the edges. Thankfully, the translation seems to have improved significantly, making the story much more enjoyable. The promotional manhwa definitely piqued my interest, and I'm glad I stuck around to see the ...

Death Is The Only Ending For The Villain
4.0
(925 ratings)
Genre: drama, fantasy, josei
I’ve reincarnated as the reverse harem game’s villainess, the one and only adopted daughter of the ducal Eckart family. But the difficulty just has to be the worst!
First Impressions
"Death Is The Only Ending For The Villainess" is a wild ride, to say the least. This novel definitely stands out in the crowded villainess isekai genre, and while it captivated me, it also left me feeling conflicted. Initially, I was hooked by the premise. The game-like elements, with Penelope having to make choices to avoid a gruesome end, added a unique and thrilling dimension. Seeing her fight tooth and nail for survival was incredibly compelling. I quickly became invested in Penelope's journey, rooting for her to overcome the impossible odds stacked against her....

(475 ratings)
Genre: action, adventure, comedy
Gu Yangcheon commited a lot of evil while serving the Heavenly Demon. But now Heavenly Demon was dead and Yangcheon became a prisoner of ‘Celestial Sword’ Wi Seol-Ah, the heroine who vanquished his master.
First Impressions
"Childhood Friend of the Zenith" promised a blend of martial arts, regression, and a touch of the demonic, so I dove in eager to see what it offered. After spending some time with it, here are my impressions. The initial premise is definitely intriguing. We have Gu Yangcheon, a former subordinate of the Heavenly Demon, reborn with a chance to rewrite his past. The regret and drama hinted at in the early chapters definitely grabbed my attention, and the idea of a protagonist grappling with past sins while navigating a new life is compelling. I was hooked immediately into the story....

(292 ratings)

What got summoned was the world’s strongest sociopath. His ability is one that allows him to buy anything, [Heart of Gold].
First Impressions
"I'm Sorry For Being Born In This World!" is definitely a web novel that provokes strong reactions. Diving into this story was quite the experience, and I found myself wrestling with its unique elements long after I finished reading. It's a wild ride, to say the least, blending dark themes with moments of unexpected humor. The initial setup is certainly intriguing: a mass murderer summoned to another world. I was immediately drawn in by the premise and wanted to see how the author would handle such a morally ambiguous protagonist. The early chapters throw you right into the action, and I appre...
