Honestly amazing.
Iffy concept, incredible execution. Love the character interactions and the art is expressive. Great read, though it might be a bit weird, given the brother simp.

Hela cool

:)

Damn bro.
Now where's the isekai spin off, he got hit by truck kun right?

Hot twink with massive intellect fights school bullies cause he mad.
MC has ultra instinct not because of instinct but because of big brain. Epic fights, great characters, excellent development. Its an enjoyable read would definitely recommend.

8 heart to heart fistings/10

Single best henta... I mean manga i have ever read.
Goofy, silly, outrageous, funny, extremely homosexual (I think), dumb, absurd, crazy, 100% inspiring, has mythical references for days (kinda like fate), ridiculous, 'I'm a bout'a CUUUUUUUUUUUUUUuuuh', stupid and home to the single best sword in all of existence.
That's enough description.

W manhwa clearly a masterpiece in the making... shit, it got canceled.
Oh well, its a good story and the canceling wasn't too outrages. It more felt like the story kept going just without any updates, bit sad but great otherwise. Setting is the typical murmin world, and... ok that about it for the setting. Story is a bit hard to describe, its like an ant colony slowly getting its foothold in a forest. It struggles at first at some point the growth of the colony starts exploding, but its still and ant colony kinda small compared to the big forest. In all its quite refreshing, the mc isn't arrogant but he isn't cowardly either, he just does what he wants and relatively powerful within his world (idk why people focus on power so much). Also i'm pretty sure this shares universes with The Fist Demon and potentially other manhwa of the same author.
Overall great

W manhwa, no cap fr fr.
Anyways the story is great and the pacing is alright. It does go on tangents once every while. While set in the standard murmin world, the manhwa does have its quirks, specifically the MC. That man is a man, like a MAN man, and man's gotta respect that. Guy is the definition of struggle and eventually he does get op. Here the story actually manages to manage his openis which is great, cause Mr Korean One Punch Man, Dam Ho (love the name) would have gotten boring otherwise.  
Art is incredible when you get used to the stylistic choices, although there is mild copy pasting going some minor panels.
