It's not that slow. I don't think it's good when the characters get together too quickly. But our main characters already are now, so I don't see what's slow about it now.
It's 122 chapters it too freaking slow believe me. No one likes it when the characters get together quickly, but this is too slow paced I ran out of patience long time ago. Any manga/manhwa that reached 122 chapters it'll probably be more deep in the story compared to this one
How much more deep are you thinking? We've gotten backstory on near everyone, but I look forward if there are anymore. This is fairly normal pace for romance manga at least. And if you want to talk slow, try skip beat. Nearly 300 chapters, and the main couple are just NOW confessing to each other. And it comes out once a month, so that's long over a decade we waited for that. To me, anything shorter than that is alright.
I'm really surprised there are people still interested in this manhwa. The story is verrry slow and cold. The art is great though, such a waste of talent and time.
