Hmmm.... I read the 1st chapter of it... but I still prefer the this manhwa, actually I can't really compare it since it is very different. I am currently reading the novel of this manhwa, and it got me all hype, it is all mysterious, from who is really cale and what he is in his past life. The mc in the THDCLaNL feels like he emits the aura of choi han. If choi han is in the 1st chapter he would beat the bandits up and cale would just watch him... I really don't know it is just opinions and preference ╮( ̄▽ ̄)╭
I don't like to compare manhwa but I like this one better typically the character dynamic Cale have. Maybe THDCLANL is a little to basic I guess? It goes like most stories goes as the mc is central of attention and a bit too brutal? I also like medium pace better. It don't develop too fast like THDCLANL which make the story kinda hard to keep up with and usually get boring quickly to me. Other than that I'm fine with reading both. Oh and I like the art style here. It has details and more eye catchy.

I just recently read the first few chapters of the plot of "The Heavenly Demon Can’t Live a Normal Life" and I wanna talk about why I personally didn't like/prefer the story of Cale The Trash Count over it:
The MC Cheonma Baek Jung-hyuk was a brutal bloodthirsty martial art demon grandpa who gets reincarnated as the moron Duke's son Roman Dmitry with already well built ideal body.
"Roman" warps the plot and characters basically everything around himself to be the center of everything when he a former nerd loser suddenly single handedly starts killing bandits/criminials with ease and sadism.
I would say the plot is very simple, fast paced, pretentious, full of primitive heterosexual arrogant two dimensional tall macho super mascular men punching or swordfighting each other.
It is a very grand male power fantasy how an op larger than life asshole can easily massacre/torture other evil assholes.
And the female characters are... See it for yourself...
I am sure you ve seen this savage martial artist gary stu type with a huge superior complex plenty times before...
What I like about the story of Cale The Trash Count...
He is unwillingly in the center of the plot but many other characters regardless of gender + race are getting the spotlight and have their own agency.
There is really sth very endearing, humble, kind, human and unusual about Cale.
He hides his real strenght/intelligence as good as he can, he doesn't like to be in center of attention, doesn't care to be on top of the hierachy of sth, doesn't show off his manly body or manlyness, doesn't like brutally torturing slowly or painfully others, is very careful considerate & respectful but also sometimes bold + sassy/cheeky, wants to be left alone and live peacefully, despite being "powerful" he still worries + struggles etc...
I really adore TRASH COUNT and his supporting cast!
If you read THDCLaNL, what arguments would you like to add?
