The ending was really rushed. There was a lot of potential in the story, but a lot of questions were left unanswered. We really don't know what god's purpose was, what happened to Seunghyun and god's deal, why god had chosen Seunghyun's family, and much more.
The plot and the art were okay but the ending was really abrupt. 3/5
I thought it was only me, but when I read the comments, I wasn't alone.
There were too many (irrelevant and similar-looking) characters that made the plot a mess. It kind of feels like the relationships between them was dragged and rushed at the same time, which isn't a good sign.
The art was nice, though. 2/5
The story started good but now, it's just a toxic mess with overexaggerated yandere elements.
