I don't really know if you'll like them but I'll suggest some
-mercenary enrollment
Good plot, strong MC, an MC that's protects the people he cares about, and an overall good character.
-volcanic age
It's a manhua, reincarnation, strong Mc, Mc with a goal in life, semi harem but not to extreme, good plot, but like around chapter 100 or so it got kinda boring but still good
-my dad is too strong
Good to binge read, strong Mc, taking care of a kid, the Mc is emotionless and tiny bit clueless.
-solo leveling
Idk if you read this but it's a very good manhwa and it's really popular
-beginning after the end
Funny Mc, strong Mc, reincarnation, you'll see the Mc grow up to be strong af, used to be king Mc, overall good plot, the art is great and all the characters are loveable except for the annoying ones
So, that's all my list that I've read so far that I think is good
For the people that likes
-action manhwa
-no harem
-OP mc
-Mc with a male semi op partner
-comedy (tiny bit)
-straightforward mc
This one's perfect for you. The Mc isn't dumb and actually has a goal. He's sometimes emotionless. He can and will kill you if you annoy him. So, for anyone that likes a antagonist this good for ya mate
