i've also wondered about that tbh idk there's also a cover that's the same as you described but pink instead of red i wanna know too
I seen a various of colors but the same way. The cover is made smaller so that the background color pops. I seen blue,pink and yellow too I think
As far as I'm aware, it's Bomtoon's banner graphic style, the original publisher of these manhwas.
ahhh okay thanks for the reply
I keep seeing a reoccurring theme in some bl manhwas. It’s the official bl cover but its size is smaller and there is a red background for it. the translation for those are really good so I thought it was the translation group’s way of ‘watermark’ but the translation groups are not the same for them. I wanted to follow and see if they post any other manhwas caz I like how well it is translated. Why do some manhwas look like that??
