I Fell in Love at First Sight, Sir Hidden Villain!


Links are NOT allowed. Format your description nicely so people can easily read them. Please use proper spacing and paragraphs.

Duke Adler, who is called the best man in the Asgard Empire, is as handsome as a statue… no– is a serial killer and hidden villain in this novel. And Princess Charlotte, whom he married out of convenience, is mu*dered on the first night of the wedding.

…the thing is, I am the princess who was fated to be killed by the hidden villain on the first night.

“It’s an arranged marriage anyway, and we don’t even want to see each other’s faces, so we’ll only meet on the day of the wedding.”

It is clear that the hidden villain is reluctant to marry me. So my choice is…

“I fell in love at first sight. So go out with me!”

Only six months left until the wedding. I decided to do an undercover investigation under the pretext of dating. People don’t believe me, so I’ll have to find the evidence myself.

While I was by his side trying to lay bare the fact that he is a serial killer…


“You said you fell in love with me at first sight, what were you doing with another man?” a cold voice flowed into my ears.

“What, what do you mean? It was just a dance to get the banquet going…”

The nape of my neck heated up from his hot breath that touched my earlobes. The cold voice and the contrasting sensation made me even dizzier.

“In his arms, you affectionately called him by his first name.”


I held my breath because I couldn’t keep my mind from the intense musk scent that wrapped around my body. My whole body was tingling from the strange sensation that ran along the back of my neck.

He tilted his head and said, “If there is another bastard’s scent on your body… I will kill him.”

It's a breath of fresh air. I absolutely love the ML's reactions to her constant confessions and the way he reacted to her winking and her asking about showing her cleavage at a gathering. My best reaction is him spitting out his tea at her first confession.

Update: Now that I've finished the novel, I can completely say that they are the cutest couple I've ever seen. She stops suspecting the ML of the serial mu*ders around chapter 80 and she finds out the true culprit at around chapter 90-something.

The FL manifests some healing powers which turns out to be a special characteristic of the royal family which was lost over the years, she was then made a legitimate successor and became crown princess.



If you wanna read the full novel, you can go to the spoiler forum. The translation is a bit off though.


The ML and FL finally confess at some chapter and later have their second kiss. (Their first kiss was whilst she was doing artificial respiration.)

The ML and FL are one of those couples with ZERO luck in kissing, every time they're about to kiss, someone bursts in the room and says that there is urgent news. It's funny and slightly annoying.


The FL gets pregnant at the end of the side stories but we don't see any children.



The true culprit to the serial mu*ders was the ML's stepmother.


I also love the change from noble + crown prince to crown princess + noble.

Also, that Archduke Killian guy was a complete snake, he was annoying from the start but he somehow kept getting worse to the point my mood was ruined every time he was mentioned. The ML was adorable with the fact that he was willing to give up his pride for the FL and the way they cuddle. Really reminds me of my lonely life... <<less

This novel is crazy adaptation based on sherlock Holmes.

Plot is nice, funny and some secret detective stuff plus romance.i have read Mtl of this novel.

FL goes from ignorant brat to loving crown princess of the empire.

... more>> ML is a such cutie and a big green flag. He's totally smitten by her. He's like a big pup. Their interaction is like breath of fresh air.

FL complements ML like crazy fan but it's all a scheme for her investigation but she fall in love with him as he's so pure and nice.

We also have john watson yup.. the og name from sherlock and he helps FL a lot. he is kind of 2nd ML but he respects her and like her more than love

Archduke killian and empress party is tr*sh. I just hate them.

Story is nice 4.5/5... go for it guys <<less

Pretty good and funny, it's basically a romantic comedy about crime solving detective (transmigrated into role of an unpopular princess) and gang trying figure out who the serial killer is ; highlight for me is how well the different points of view are done for multiple characters

Characters:... more>>

MC is fun brash, smart, and suspicious of basically everyone

ML is a traditional distant at first but actually sweet doof falling hard for our girl who just wants to hear he did a good job

Supporting cast: falls a little short so far in that the only characters fleshed out are potential love interests but that's okay


My only complaint is that there are too many Sherlock Holmes references but that's just a personal preference and it is cute sometimes <<less
