How is it irritating? The art from Kiss me liar is very inconsistant and to me the style very off-putting in comparison to this one.
Didn't say he looks bad, and I think the hair color now looks more like in the novel than in KML . I thougth that his hair would be slicked back, because I had that feeling when reading the novel, but it's bound back in the manhwa. But we only see him from the back and from the side.
If you have a good addblocker take a look yourself https://newtoki468.com/webtoon/45529430?toon=BL/GL or wait for the translation.
I see your point i also thought his hair was slicked back
The appearance of Grayson at the end took me by surpise. For one in the novel Josh meets him outside the house by his car first, different clothes and wearing sunglasses. They changed it in the manhwa. And the art is a bit irritating.XD
