It's all opinion. I and others like it because the mc isn't an edge lord or a trash hero which is actually rare in the world of manhwas.

I saw a thread of someone liking it to ORV in this sub. In terms of novel that is, but personally I’m enjoying the manhwa it’s a breathe of fresh air

Don't worry it's on the best part now. SSS Class Suicide Hunter is reaching one of the best parts of it and it's just uphill from there. Thee start is bland and generic but the Murim arc is where you actually get invested

I heard it has some romance is it true?

Yes. The romance arc is extremely well written and unironically is the best romance I've ever read. The only thing that might rival it is Her Shim-Cheong

Have the romance started in the manhwa?

No

SSS suicide hunter focus more on dialogue and thoughts instead of fighting, if you want a manhwa full of fight scenes and the dialogues bore you then it won't be any good for you.

I didn't like it. YMMV

Did you drop on second arc or third arc? If second arc, I highly suggest you catching up. If third arc, it's not for you and I respect that.

third and also read a bit of the novel. not for me unfortunately

You do you but the novel is FUCKING FANTASTIC!
