I’m pretty sure there is one (u prolly just missed it), and I mean that this manhwa (Paradise on earth) has the same art style as pyramid game (since I saw it in the congratulatory message for surviving romance) which proves ur point, not that paradise on earth is similar to surviving romance. not to be rude but I think you mixed up my comment with the other guy’s comment (anyways idk why I wrote such a long explanation, and idk why that guy said their art is similar since it really doesn’t seem that way to me either)
i guess it comes off similar for me because i just love LOVE artstyles like theirs that gives off 2D dress up games - they color, shade, and highlight very differently, but the way they draw the girls’ body composition and eyes seems similar to me at least. they also remind me of the artstyle that an animation

this seriously reminds me of the manhwa i used to read called ‘survive the romance’ where the fl gets sent to a novel/drama she waas reading and force to live a romance that never ends, until she starts going against the narrative and the story transforms into this horror type shit.
my favorite genre, romance turned horror
