I feel like I'm reading a 90's style manga except in color...which is worse.
Usually, if the art is simplistic/amateurish I can ignore it if the story itself is captivating. (Or I'd never have survived the 80s and 90s as a shonen anime/manga fan.) But this is just plain ugly.
The MC is hard to look at. The side characters are even worse. MC is too unlikeable.
The action, what there is of it in a series like this, is static. There's no hype moments even though there's a bunch of colorful shit that's supposed to clue me in on This is IMPORTANT. But nah. It doesn't come across that way.
I know manhwa, especially, takes a painfully long time to get the point. A lot of the time I find that if I give it to around the 70 chapters mark it starts getting good. I don't know if I have the patience for that here. There's nothing incentivizing me to stay.
I don't mind when the MC immediately starts using their cheat. I prefer it, in fact, but this MC was never good at his job it reads like. He has no opinions of his own. Oh, some auntie told him he should open his own clinic?! Okay! That was what he immediately went and did.
He takes his girlfriend for granted. I mean, 10 yrs of dating? Wow. I don't blame her for finding another man. Obviously, I blame her for cheating but nothing else.
Some asshole he calls his hyung/brother tells him he's shit by himself? Okay! He'll shut down his business and go to that hyung's hospital to become a therapist instead!
There's zero repercussions for him for closing his business. He doesn't angst about it for too long either. There's something about a loan but considering how it was given maybe two panels it doesn't seem like a big deal. He can just happily skip off to the interview at the big hospital now!
He used the wrong kind of treatment for a customer and the System has to tell him he's wrong. Sure, maybe it's for dramatization but now we're in even more trouble. That means the writer is incompetent.
All of this together is not looking too good for this manhwa.
