Today’s topic is gonna be really interesting!

I assume you probably know what manhwa is, right? Don’t tell me that you clicked on this blog that is based fully on manhwa, and you have no idea what manhwa even is? Bruhhhh! Well, I guess I have no choice but to explain what manhwa is.

Manhwa are basically manga but written by a Korean author. I don’t think I need to explain what harem is, right? You probably know about the harem if you are a true weeb, but if you don’t know what it is, then I am sorry but I don’t consider you a true weeb.

Enough chit-chat, let’s start with our today’s topic, 15 Harem Manhwa with An OP MC.

Memorize follows the story of our MC, Soohyun. Soohyun was an ordinary teenager living his life to the fullest, until one day, he got transported into another world that almost looked like some kind of game.

Who summoned Soohyun? You may ask. Well, it was some kind of angel that summoned him into this world. For the next 10 years, he worked hard each day and finally, one day, he became the Apex.

He should have been happy right? I mean! Becoming an APEX of the world is too good. Well he wasn’t. Why? Because his life was filled with mistakes, and deaths of his loved ones. He wanted to go back and try not to make those mistakes and live his life to the fullest.

He used the power of something called Code Zero and goes back 10 years where it all started.

Do you believe in aliens? Most would say they don’t. Personally, I don’t really believe in aliens as we don’t have a lot of proof regarding aliens or ufos and stuff. 

Heaven’s Soul follows the story of humanity and aliens. One day, aliens decided to attack humans and now, humanity is on the verge of destruction. If nothing is done fast, then humanity is done for.

We have all seen manhwa where people fight monsters or aliens, then the OP main character arrives and destroys his opponents right? I don’t wanna spoil too much about this manhwa, oh and there is a bit of harem in this manhwa at some parts!

The Second Coming Of Gluttony follows the story of our MC, Jihu Seol. You see, Jihu didn’t really have a good life. He was weak, by weak I mean REALLY weak. Now you may ask, “Isn’t this list supposed to have OP MC?” 

Well, Jihu may seem weak, but he has a REALLY OP ability that I won’t spoil for ya! With the help of his newly found ability, he goes on a journey to survive in this world and become even stronger than he currently is, because if he doesn’t then…

There is like 0% chance that he will survive in this world.

P.S: I forgot to mention but he was also an addict.

What comes to mind when you hear the name “Wizardly Tower”. You would probably think of some kind of tower that has a lot of wizards in it and stuff, right? Well if you did, then you are wrong.

How did he come back to life? You may ask. Well, it was due to some kind of experiment that went horribly wrong. When he came back to life, he met Ere and Are, and then set out on a journey to get his tower back.

 

Conclusion

This is sadly the end of this list, for those who are triggered at me and are saying “Is this guy saying this manhwa is better than the other?” If you are saying that then, you are wrong! All of the manhwa mentioned on this list are amazing in their own way!

To be honest, it was really hard to find Harem manhwa with OP MC because this harem OP MC stuff isn’t that common in manhwa unlike in manhuas, so most of the ones that I end up finding were manhua.
