Do give it a try! It does have some wattpad-ish vibe but plot and character wise it's wayyyy better than flashlight or other similar manhwas.
The plagiarism thing: shutline's author once accused flashlight's author of plagiarising her work because the characters have similar traits (blond westerner top x black haired korean bottom) but clearly the flashlight author didnt plagiarize cause flashlight is shit

I didn't read Shutline cuz honestly, I didn't like the blonde dude's hair (we listen and we don't judge). But given how this story has gone completely south and everyone's saying that Shutline is better, maybe I should give that a try. Someone also mentioned something about a plagiarism rumour. What's that about?
