I could appreciate how realistic the portrayal of each character's thoughts and reactions was. As an example, the MC's emotions were actually very relatable and a natural reaction to trauma, which is why he experienced drastic highs and lows. This realistic characterization might not appeal to younger readers who can't empathize with others.
The problem is that the main couple's development is odd, both for the reason Min Gyeom falls in love and for the circumstances under which they finally get together. Then, the ending right before the side stories is pretty sudden. Thankfully, despite the drama in the epilogues, you do get scraps of more content about them as a couple and you learn more about Chun Sam's parents, who are one of the best additions to the narrative.
Before concluding this review, I'd like to remark that the art uses very dead colors and there often aren't any backgrounds, giving the world an empty and hollow feeling. This dead atmosphere improves towards the end of the story, but it's still a fault worth mentioning.
