    https://www.novelupdates.com/series/overlord/ - The best of the best but with extremly evil main characters. It may be depressing for you if you like THE GOOD to prevail

    https://www.novelupdates.com/series/the-new-gate/ - I like that one very much but there are a lots of people who do not. More realistic then other LNs. Not harem like romance but MC is surrounded by few girls. Sad moment in the past. Overpowered MC who does not like to be known - this is the most dissapointig for most of this LN opponents

    https://www.novelupdates.com/series/hataraku-maou-sama/ - fantasy comedy

    https://www.novelupdates.com/series/isekai-ni-kita-boku-wa-kiyoubinbode-subaya-sa-tayorina-tabi-o-suru/ - quite peacefull slices of life in a fantasy world. If you like no harem romance you should like it. You liked  "I, a Demon Lord, Took a S*ave Elf as My Wife, but How Do I Love Her?" so it should be good for you.

    https://www.novelupdates.com/series/the-amber-sword/ - I liked it and I have written positiver review but after reading most of the story I was dissapointed a lots of times. You should find it out by yourself.

    https://www.novelupdates.com/series/my-death-flags-show-no-sign-of-ending/ - I dropped it but it is decently written. This LN has a lot of funs. For me: too much artificial saddness.

    https://www.novelupdates.com/series/summoned-slaughterer/ - I like it but lots of people do not as MC is psychopatic mu*derer

    https://www.novelupdates.com/series/isekai-maou-to-shoukan-shoujo-dorei-majutsu/ - ecchi fantasy isekai. Quite decent and hmm... normal for ecchi.

    https://www.novelupdates.com/series/demon-king-retry/ - not finished. As people like the anime maybe author will continue to write it. Right now it is hard to say if this LN is good or bad

    https://www.novelupdates.com/series/magis-grandson/    - low level novel but lots of people like it

    other: The rising shield hero, Swords art online (I am not going to read this but 1st anime series was good),  No game no life ("no game no life zero" spin off anime is a masterpiece) , gate-jietai-kare-no-chi-nite-kaku-tatakeri (I liked the anime but I will not read LN) , Re-zero, Log horizon, Drifters

      Thanks! I add some of them now. Can’t believe I forgot Overlord until you reminded me, also The amber sword is a Chinese novel.

    Btw I just thought I'd state that Oukoku e Tsuzuku Michi has a few people in the harem who have cheated on the mc. One of them also has done it multiple times. This is just what I've seen from the wiki. I personally haven't and don't plan on ever reading it.

    https://www.novelupdates.com/series/tsuki-ga-michibiku-isekai-douchuu/- Tsuki starts out as an action Isekai but it quickly evolves into a world building political story since the MC is dedicated to being a merchant and he can't just freely amass power since the goddess that summoned him is against him. it's on the same level as Soudoki and Sevens which you also have on this list 

    https://www.novelupdates.com/series/little-tyrant-doesnt-want-to-meet-with-a-bad-end/https://www.novelupdates.com/series/little-tyrant-doesnt-want-to-meet-with-a-bad-end/- This one is a really good read it's the same concept a "Trapped in a Dating Sim"  as the MC is reincarnated into an Otome game, but he's the main villain who's destiny is to be killed so he's trying to change the future. I like it cause each of the romantic interests are all really likeable once you get to know them and it's realistic in a since cause they all come from different standings. The funny part is as a slight spoiler, all his interest are the girls who kill him in the future so there's a bit of comedy in the MC trying to avoid them but ending up getting involved anyway.

      Thank you for the recommendation bro, but I’ve read them both before and the reason I’m not include the first one is: it’s not focus on either of romance or harem which is the main focus of this list. And the second one is a Chinese novel which I also have in my other list.

      @Shut it Understandable. I didn't even realize the second one was a chinese novel until i was about 100 chapters in. The translation is just that good

      Just go to each of them to check. If it has a manga version, they will have the Adapted to Manga tag there.

      Well I said Romance/Harem not Romance + Harem.

      Please look at the title clearly before make a comment like this friend. clear.png
