Contrary to above critique, I find this comic to be quite comedic.

The main aspects of this webtoon are comedy and smut scenes. It was funny how the main character tries to sell useless products again and again. That was the best thing about the whole webtoon. The smut scenes were often forced and I was no fan of them, but they're ok I guess?
Though there was no really deep plot, it was ok… It's a rather light story.

What annoyed me most, though, were the characters. The main character is quite dumb, but bearable.
His love interest, however, is a real bastard whom you'd love to smack and hand over to the police as soon as possible. After half of the story his personality suddenly took an unrealistic turn by 180°. Seriously, he changed so much in personality and appearance that he seemed to be a completely different character. I've never seen such a terrible character development ever before. It was, simply put, creepy. He became so different that I even wanted the sadistic asshole back which he was before, just because that side of him seemed more human. And because of the sudden change, the main character also suddenly saw him in a different light even though he hated him until that point. I think in the first half, the manhwa was still fine, but the change in personality killed everything.
And what's the deal with the cute acting guy with freckles? Is he a god or something, being able to pull so many strings?
The best character by far was the pink haired dude. Though I didn't get what his aim was the whole time. But yeah, he was quite normal and cool — which is a rare find in this manhwa.

Concluding, the good point about this manhwa is that it will make you laugh. Not enough to make up for the creepy characters though, in my opinion. I don't recommend it.
