We Monsters Are Not Allowed to Be Single


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

After the 108th Monster Population Census, the Monster Family Planning Office issued a new regulation: Given the rising single monster population, which poses a threat to the society and undermines the harmony between humans and monsters, Monster Family Planning Office decided that from this day onward it’s forbidden to be a single monster of marriageable age.

As a result, Ying Qiao and Tao Tie, two ancient monsters who had remained single ever since their creation, were forced to go on a blind date.

To discourage their date, they both decided to lie about what they truly were.

Ying Qiao: “I am an orphan snake monster with no house and car under my name. My monthly salary is three thousand yuan. Can’t afford social insurance.”

Tao Tie: “I have a temporary job and eight brothers living off my eighty yuan daily salary.”

They both agreed they were not a good fit for each other. But under pressure, they agreed to put on a show to set a good example for the benefit of the new regulation. They planned to be a fake couple.

A foreign monster entered their nation illegally and committed many crimes. Jiang City Monster Bureau was put on high alert, and elite members were deployed to hunt for the suspect.

After having his dragon scales polished, Ying Qiao spread his wings and joined the hunt.

Putting his brother into his pocket, Tao Tie went out to join the hunt too.

In the sky above Jiang City, they had a chance encounter.

Curling his tail to hide his expensive jade tail ring, Ying Qiao said.” I am on a business trip.”

Putting his hand behind his back to hide his wristwatch worth a million, Tao Tie said.” What a coincidence, so am I.”

Knowing that their lies were exposed, they stared at each other long and hard. They both said, “We will settle accounts after getting back.”

I really loved the concept. It's pure fluff and doesn't really have much misunderstandings actually.

... more>>

Unlike the deceptive synopsis, both MC and ML actually only have that moment where they realise their identities and then work together to deal with the enemies. There's no substantial misunderstandings/ arguments that takes place and both accept each other's hidden identities fairly well since both lied to one another.


There are horror elements mixed in too. I think it's upto the initial 120 chapters. Both MC and ML are OP respectively but unaware of each other's OP statuses.


MC: He is a Tao Tei who is greedy by nature. He loves to eat and can engulf almost anything and is really hard to satisfy. His background story is pretty sad too. He was born (or more like created) from the grievances of another ancient beast and was later on discarded by his own clan since they felt he was born too s*upid and only felt hungry every day. Later on, when he broke free after being sealed, he stripped off his "grievances" to a large extent, thus restoring his sanity back. Later on he got accepted into the Dragon Palace and worked on his attitude to become a better person.

ML: He is a Ying Long, another ancient creature, a dragon known for its prosperity and good luck. He participated in the war between the monsters in the ancient times which finally ended in the path of heaven and earth being cut off. He has since lived on earth as Ying Qiao as the deputy of the Demon Management Bureau.


It was actually fairly enjoyable. Both Jiang Ran (MC) and Ying Qiao (ML) maybe started off on the wrong foot but they really cared for each other. I loved the side-character interactions too and how the brothers of the Dragon Palace are close to the point it's comical. I thought it might have mpreg elements, since most monster-based/ beastman-based yaoi I read on NU have mpreg and the select few ones are shounen ai. But it didn't. Thank goodness of didn't because there are already side characters who add to the fluff. Anyways it was a great read. Enjoyed it. <<less

I don't know why this only has a 3.9 stars but sod off, haters.

I haven't finished reading this but I'll give you what I think about the novel.

It's a pure fluff concept, dog foods thrown to single dogs left and right. The ML and MC are super cute and compatible. MC who just left his home with his younger brother has always been starving; food with magic can only satisfy him. In order to support himself and his younger brother, he accepted a blind date for 20, 000 yuan.

There he... more>> met ML who thought he was poor and thus began his cub raising program. LMAO!

Both of them lied about their identity.



is a dragon called a Ying Long who's a boss and definitely doesn't have an 8000 yuan wage but he lied to MC saying he's an ordinary snake monster (or demon in MTL) with the wage of 8000 yuan. Has a bad reputation as Ying Long.


is the Tao Tie, one of the "four evils" in ancient times. Tao Tie is said to devour everything in his path and people have a bad impression of him because of rumors; hell, when ML badmouthed the "Tao Tie" in front of MC, MC went mad. He lied to ML saying he's a lion monster with a wage of 80 yuan.


And thus began their misunderstandings. :D


They have 3 children to care for. MC's brothers, the lion dragon, a conch dragon? (Not sure, in MTL, it didn't specify him) called JiangTu, and a kid they picked up along the way.

Still near the beginning and I am intrigued. The summary explains most of it, two 'monsters', or ancient creatures/ deities exist and because their numbers are low they must date. Our MC and ML were set up on a blind date, and wanting to sort of get out of it, lied about who they are, jobs, etc to put the other off. Due to some manipulation though they decided to 'pretend' date and set a good example to other monsters.

From there a few more misunderstandings happen which are hilarious, where... more>> they keep trying to hide who they really are and explain away certain situation. Its funny, well written, and beautifully translated!

I can't wait to see what will happen next. <<less

Super cute story about two rich and powerful ancient yao pretending being normal yao. Super hilarious especially when Ying Qiao thinks Tao Tie is very young because he has baby face and so he thought to raise him as his baby but than when he saw his body, he was like wtf where was my eyes he obviously adult!!! I laughed really hard on that😂 when you understand that Tao Tie too though of him as very young man who he should try his best not to fright it double... more>> hilarious. Cute brotherhood of Tao Tie and his brothers, and Ying Qiao's money grabbing secretary who he made to pretend his boss, too super hilarious. Especially when everything was relieved and he was like you two ancient grandpa and I'm little baby (2k yo khem) lol It's cute and fluffy story with some everyday cases from their work and mystery from the past. Liked both glutton Tao Tie who looks on his enemies as food and narcissistic drama queen Ying Qiao. <<less

I’ll come back when there are more translations

Right now my rating is 3.5

I had really high expectations but the ML is bothering me lol. He keeps saying that he treats MC like a young cub and interacting with MC is like raising a cub — I don’t know how ML got that idea but it’s kinda bothering and cringy cause MC is already an adult, he may be thousands yrs old or something but his human form is that of an adult. Plus it’s not like MC just became human... more>> yknow.

I just dislike how ML keeps comparing and thinking of MC as a “young cub to raise” because there seems like no apparent reason for these thoughts like it suddenly came out of no where which makes the ML cringy to me

But this novel is like “Non Human Sub District Office” or “Don’t discriminate against species” which are cute so I’ll give this another chance/read when there’s more chapters

I saw that they figured each others identity at chapter

I just love this novel and I just wanted to say it. The MC and ML interactions are pure gold haha so many cover-ups and some of them are just so hilarious and no one is suspecting anything, thats probably the best part, ancient monsters but their brains don't seem to work correctly all the time. You just wanna laugh or at least I did. No third-party dramas or b*tchy characters so far and the fluff is just too great. Can't wait for the next chapter especially now that it... more>> is getting a bit hotter. <<less

feel like it's a bit overrated.

i enjoyed it yes, but I also had to skip and just brush thru various chapters.

It felt a little plain and sort of lacked some excitement in regard to the whole hidden identity, big bad ancient monsters...

it's got a good flow but the protagonists got together a bit abruptly IMO. like it was a slow romance but when it did happen, the build-up didnt feel complete. the ML is so good with the MC's younger siblings and I love that and tbh this novel... more>> is a bit low on the comedic effects that would uplift this.

not bad but not memorable either.

still loved the world background and building tho I felt that whole “no monster of marriageable age should be single policy” seemed nonexistent after the first 5 chapters????

like ok (???) <<less

This is one of my fave novels right now. The story's great - the misunderstandings trope really works here. The translation's also top of the line! Patiently waiting for updates :D

Overall quality is good, interactions between MC and ML are based on a lot of misunderstandings, which makes it funny, the big reveal was around 100 chapters later.

ML thought MC was a cub the whole while and tried raising him as his cub, the way he tried was cute.

As the summary, the story started with that blind date😂 anyways they got together then was shocked with the other true identity by 100 chap+??

More on solving mysteries/monsters crimes throught the story + finding why the upper &lower got divided.

The cubs are very cute, there's also some side couples.
