It's been a while since I've read a story that doesn't have regressions, isekais, transmigrations, some kind of transformation from an item, system, etc., or some such plot tools, how sad it is that just not being among those makes a story somewhat fresh in recent manhwa.
This one is about a kid born with some sort of dark seed that's abandoned and survives against impossible odds thanks to the seed and an altruist leopard. The story (so far at least) is mainly him getting stronger, learning to control his demonic surges and struggles to live along humans. As it often happens, he meets one evil or bully per decent person. Because of a setting I won't spoil the MC can't kill (or shouldn't), this is a bit of a bummer, I don't like MCs that murder for the sake of it, but letting go someone that will pose danger later isn't smart either, balance is key.
The good, is a cold collected MC that doesn't overreact over every little thing and doesn't go collecting a harem or acting like a perv, he also doesn't seem to be blinded by gold, all good if a bit bland, given he lived isolated maybe he'll change with exposure to society.
Other big one is the art, the char designs are good, but nothing special, the backgrounds and details on the other hand are amazing.
Overall, a good read, nothing great so far but has potential.
Edit: The second season goes into the recurrent "academy life" arc, which derails from what made the story interesting in the first place, the end of this season on the other side is a good improvement. As for the 3rd season, it's still ongoing but for the time being it seems to go back to an MC centrist focus, to be honest I find the MC too adapted to city life and human interactions given his upbringing.
I don't dislike the new route the story taking, but I have to echo others' opinion that it's not as good as I had hopped. Which is a standard, a good start to fail to maintain an interesting story. I hope it improves but I'm not holding my breath.
