Btw. i'm still happy about more recommendations and/or self promotion =D
Just try to keep in mind:
- Actually harem/polygamy setting
- Nothing really sad (death of potential harem members and stuff like that is no-go)
- For new novels it would still be nice to have 50k+ words to actually have something to read & judge.
Thanks =)
Sorry about that. I was only looking at the fluffy part.
In that case, how about? On-going.

This one is 1mil word and equivalent to 1k to 1.5k chapters. The chapters are long sometimes. Status: Complete.

Nebel Hmmm, recently I've been reading this one
https://www.webnovel.com/book/part-time-star--full-time-dad_13532459105151605
So maybe if you want to try it too.....
I think its "fluffy", and its also Harem. 
Oh, this one is also okay if you could just think incest is okay since its fiction (I also disagree with incest IRL), and MC (at least the inside soul) is not really the girls family, while his body are of course their family.

The super duper fluffy parts comes after you manage to keep on reading after they start the (incest) relationship. So perhaps if you really dont mind, just try reading all the free chapters before giving judgement? 
Hey Nebel, my story should match what you want.
It's 10k words so far, but I'll release between 10k - 40k words once webnovel approves my story.
Thanks a lot for those recommendations! =D
@Dyrem Mhh, i've read the first chapter. I wouldn't mind it if he stole those girls because their boyfriends treated them badly or stuff like that. But as you said, he is just despicable and i felt already bad and disgusted by him after the first chapter. So probably not a novel i would enjoy. But since you explained quite clearly what i could expect, i am still grateful for the recommendation.
@Avidfan no problem =D "fluffy" is actually the most important thing. But i really enjoy if other nice characters/cute girls also getting part of the "family" so i really prefer harem settings :x
GegeSadewa I don't mind incest tag at all. IRL i would be quite worried when they plan to have kids etc. but beside that... in animes i often hope for a happyend for the sister-character as well :x I've read 6 chapters of illicit... was quite annoyed at the start (seemed like everything was only about sex/desire)... but at the end of chapter 6 i have hopes, that there actually will be fluff later on :x BUT honestly, i am not such a huge fan of the "milf" setting and him just beeing horny about all the older woman around him...
Regarding part time dad; Not a huge fan of the setting with a child... BUT i guess it could be really cute and maybe it really has great harem building thanks to that... so i'll definitely will give it a try later =D
RazorIsSharp mhh, i guess i will wait till you get approved ;)
Again, thanks for all those recommendations!
And if you have anything else that may be fitting, i'm always happy to read more xD
Nebel Yeah, for Illicit we have to plow through the first 30 chapters or more, but after that, I think its quite all right.
I actually kinda like MILF, especially if they even could be sweet and felt even younger than their counterpart. But, to each of their own I guess....
Thanks for at least willing to try and read more of them. 
I may not be the author of those, but plenty of story need more readers with nice attitude like some of us all.
GegeSadewa If its fitting with the genre, i am willing to try everything xD
I am just REALLY bad with sad stuff, so i try to find some spoilers if any potential harem members die, get rejected etc. and really avoid anything that have stuff like that.
With the harem setting... i just really like it if its fluffy and all the "nice/cute" girls around the mc can get a happyend together. I'm more into the fluff of romance and beeing a family as well as the harem building/reasoning itself. I could live without all the sex stuff, but nearly all the time its kinda related and i don't really mind it and/or can skip it
Ohh, btw. i also started reading your other recommendation "part time star full time dad" and it was quite fun. If you read the part above you can image that i wished for some more romance instead of the ...+ relationship thingy thats going on atm. and the girls only "accepting" instead of caring for each other. But its kinda realistic and there is room for more so i really looking forward to it. BUT sadly the author isn't really consisted with the releases xD
And again, if anyone knows other stories (platform doesn't matter), i'm really happy about every recommendation; As long as every girl gets a happyend (haremsetting, not too sad) i'm happy and would give it a chance =D
[unknown] Btw. i continued reading Illicit (since i already running low on alternatives again xD ) and managed to get into chapter 40... but its not really my thing. Not a huge fan of the mother thing, but i could deal with it. But nearly 50% of the chapters are sex and he is to much of a playboy for my taste. I know what you meant with more romance and i totally get were you're coming from... but... as i just said, the romance is to forced, to playboy oriented... it only feels like he want to sleep with them and is sweet-talking just for that, nothing else
I think I have the perfect stories for you, but both of them are mangas. The first one is called "The 100 Girlfriends Who Really, Really, Really, Really, Really Love You". I know that the title sounds ridiculous but trust me, this one is a gem and is exactly what you are looking for. It has A LOT of fluff, every girl in the harem gets a lot of attention and is never forgotten. I would recommend you to read it on mangahub because of some problems with the scanlation group many sites don't have all the chapters and mangahub has all of them. The second one is called "Kanojo mo Kanojo" and is also very sweet. Both of them are real harems, have a lot of fluff, and are really funny. I really recommend you to check them out!
Leporidere Thanks! Overall i highly prefer flow text and mangas aren't really my thing. But those two really look cute and since i don't have much else to read i'll definitely gonna try them!
(And thanks for the source recommendation as well =D )
Don't f#$% with him. 17-year-old Hyde is a delinquent that meets his end in a back alley, but he is transported to another world on death.
One of many, Gripton, Transmigration God, helps Hyde to choose his magic but decides to stay and try and teach this boy some manners. He also gave Hyde a strong magical ability that could upend the world Hyde was sent to save.
These two will travel the world and take the nations and their daughters by storm. In a world where everyone has a magic skill and the strong rule, what path will the so-called hero take? Summoned to another world against his wishes, Hyde has his own way of doing things.
Join the foul-mouthed delinquent and Hopeful Transmigration god across a new land!
Welcome to Reborn! A place of infinite lifetimes in worlds and planes thought only to be places drawn from imagination. Players that enter this world are children stricken with a particular terminal disease and given a chance to be reborn an infinite amount of times, participating in new challenges and systems every lifetime.
Not everything is perfect, though. Reborn's creators hide the fact that players enter as NPC's and without having a supporting god, they will continue to get lost in the flow of time, losing all memories after each life. For some, they are forced to live in poverty or worse.
"Gods": Players that have won or been on the winning party at least 20 times or been granted godship through a wish.
Dave, one of the thousands of players, is a 42 years old homeless man with his memories wiped and has lived this life in poverty. One of the many gods that have transcended, Fate, stood to cross him at every turn and kept him from success. Now sitting in an alley and about to die, Dave prays to anyone listening to give him another chance.
Two gods heard this plea, for they had been watching and waiting. Destiny and Transmigration had been waiting for this moment to snatch up Fate's plaything.
As Dave gives his last dying breathes, he hopes his next life is better.
When Dave dies, the goddesses take him to a new world and explain his new leveling up system, but he realizes a horrible fact when he opens his eye.
Dave is a poor street urchin with no home. Reborn as a poor kid.
Memories of his previous life are all he has to go on, but Destiny guides him to reconnect with strangers from past lives and start him on another journey to save more lost souls. Slowly the memories with each woman reconnect and help Dave get back the experiences he lost while forming new connections and relationships along the way.
Join Dave, Lavender, Tilly, and all the rest on their adventure through worlds and as they meet new friends and experiences new systems!

Nebel
Here are some that I read and can recommend -
0 - Against Heaven's will -the continuation of - Spirit Cultivation
1 - Psychic Inventor in Cultivation World - flirting mostly and later++ things take a turn to romance
2 - In Naruto: Reborn with Talent = fanfic worth the read, only 46 chapters atm
3 - Prime Vampire = good plot, writing could improve but a good read + another work of the author is decent
4 - Trash Techniques are Actually Pretty Efficient = A comedic tone with the story that is a bit quirky, late harem
5 - Nine Venoms Sect Founder - good writing and plot, can be a bit confusing at times - ~150 chapt - late harem it seems
6 - Shadow - Unique cultivation + harem story, anti-hero - skim through first ~15 chapters to enjoy - medium/late romance improves as you read
7 - Perverted Otherworlder = comedy, fun, cultivation and shameless mc
8 - Yin & Yang Pleasures of Cultivation - Interesting story, plot and good writing
9 - The Romantic Cultivator - MC is funny, keep going in the beginning, the plot, story and characters are worth the read
10 - Fourth Prince's Debauchery starts off with r-18 leads to plot + author's other work (Science/magic - an unnecessary tragedy, in the beginning, is good after)
11 - The Sinful Life of The Emperor - a great read, MC 'steals' other's women, you will be happy and laughing most of the time
12 - A Cliché Multiverse Story - good fanfic story you don't need to have much previous knowledge of the worlds
13 - Stealing Spree - MC steals other's women there is a plot and generally with positive vibes, the start of the story is not very happy
14 - Unrivaled System - I read a while back, I remember enjoying it not sure how the r18 and romance in the harem is balanced.
Most are original work of here... If you have any other good ones share them.
Edit() PS the list is not in any order.

Nebel You can try mine, it's freshly start but quite a fluffy romance I'm aiming (not so harem, though--only spoils here haha)

Hey,
honestly, i don't know if anyone is interested about my opinion about a novel that was recommended, but i just like to give some feedback :x
SecretWolf thanks for this super long list and even with some nice explanation! I thought about starting with Prime Vampire, Psychic Inventor and Romantic Cultivator.
I didn't had much time this week and only managed to read Prime Vampire to some degree. The story is quite promising, but god i hate this mc sooo much. He only cares about his owne pleasure, fucks every girl the first time they meet and treats them SO bad in bed... i really was disgusted by him. Really sad because the story could have been quite good.
I think i will try Romantic Cultivator next, i've read that the mc is quite dense. Normally i don't like that, it can be super annoying. But atm i really need some distraction from this selfish disgusting guy (MC Prime Vampire) so i just hope that the mc here is the "shy-dense" type with some cute romance, and not the "stupid-like-a-potato-dense" MC xD
Nattychris_22 Hey, thanks but i think that's nothing for me. As i said above, i really prefer harem settings with several interesting characters that all somehow end up together happily. So yea... additionally only 12 chapters and annoying kids are another thing i don't really like :x
Nebel Hey Nebel! It's quite a new story but maybe you can keep "My CEO Harem Cultivation System" on your future to read list? 
It's currently at six chapters right now but I have plans to keep it light and upbeat!
https://www.webnovel.com/book/my-ceo-harem-cultivation-system_18550691905102105
Girl here too. I’ve read Romantic Cultivator. The story is actually fluffy and fun if you are a girl. It isnt because the MC is dense. He just set his sight on a girl that he had a romantic relationship in the past (this isnt a spoiler cos u get to read this very soon) but he doesnt trust her when he had met her again because
....(this part u got to find out urself. Because there is a mystery here).
The MC is actually quite smart and caution if you reading from a neutral perspective. But although he tries to be smart but the heroines are smarter than him sometimes so he got outwitted by them. I think this part causes some male readers ego to be hurted because they cant stand smarter heroines. They may think they r smarter but i bet none is smart to solve the mystery.
Story actually has many plot twists, touching and fluffy movenents. It is a harem story that girls will enjoy
