I've watched a few kdramas on Netflix purely because of their poster and some of them are my favourites. I started Tomorrow because I loveed the red and blue aesthetic along with the cool poses of the protagonists. And it's one of my favourite kdramas! However I also watched Doom at you service for its poster and I was struggling to finish it. But to be fair DAYS and Hotel Del Luna are the only kdramas that have let me down with their pretty posters.
