Regressor Instruction Manual

only reason its not a 5 star is because hayan the FL is SOOOOO annoying otherwise this is solid

This story had me hooked from the begging the world building was pretty decent and the characters also seemed cool. The backstory of the MC was also interesting. The Mc is friends with a regression and another friend from the past. She gives a andere vibe which was tolerable at first but became unbearable near half way. If it was just her and someone else it would have been more easier to read then it just became another harem. Girl after girls just lining up to the MC wanting to be with him. This type of story is not for me.

The comedy and the jokes were super funny and the actions scenes were funny. The art changed midway which doesn't real,t affect me much as the plot was decent. The expressions tho were very funny and that was the charm of this story and what made it mostly appealing to me. 

But unfortunately bc of the continuous harem it just Beckens off putting and at one point the plot if the story became a harem which was not my cup of tea. In the end what I say is it started off good but became bad as it feel for the harem trope. But if ur into this stuff read it but I dropped it around chapters 70.

I've read until the 17th chapter. I'm dropping this sh** though because they wouldn't kill off that fuc**** mage bi***. If they actually killed her off then it would have been a 4/5 but she just ruins the whole reading experience for me.

I like it, I like how crazy the MC is. If you love crazy and money hungry MC's you should read this😉

Best thing if u like manhwa with system , players , rggressor, manipulative mc

This story never disappointed me and it's getting better and better

I was enjoying it on earlier chapters, then the artsyle changed which I wasn't too happy with. And I felt as if this was turning into another harem. The line of girls should have ended with red head. 

There are much more ways to gather power other than gathering girls. The author just made it a harem on purpose. 

I was so excited to read this. Now It feels generic, overdone and overall has left a bad taste in my mouth.

Please add more women for our mc and add more romantic scenes!

Dropped at chapter 37. The fl is too f*****g annoing and for me she completely ruins the story. I give up.

this is really a great manhwa 5 star 
i really didn't get bored from chapter 15 and up 
good plot twist 
good art style love the character 
i don't really like harem but this is different its a good one

One of my favorites, 10 / 10 Kiyoung Is Flawless

I learned one thing while reading this : if I got isekaied, I need to keep a freaking low profile because there will always be someone smarter and more cunning to lead to my death if I mess up with the wrong guy.

Seriously, the story is really nice and the mc is really the type I like : cunning, little evil and good planner.

That little girl archmage is way too much to handle but overall, that's great.

A 9/10 from me, but for a great review please scroll down and read our beloved Ivern’s review. The princess makes some fantastic points indeed. I wish I could melt him down into a thin strand of smelly cheese and push him into my ear all day, tickling the deepest regions of my ear canal. The sensation would be breathtaking, I assure you. 

Life is hard

Masterpiece

Well da** i forgot to rate this manhwa

This story to cute hahahaha i hope i can read more of this

This is good, not gonna lie

IT'S A MASTERPIECE
It has a regressor character but it's not from the usual POV, we get to see from the regressor's friend point of view.
The mc is cunning and smart and only makes choices based on rationality and what would bring him most profit, though there are some people that dislike mcs that aren't altruistic and "good people" I love characters like this.
Strongly recommend

it took me a while to convince myself that this is not B.L(Boys Love), but i would reccomend it since the mc is smart, cunning and funny.
