The main plotline of this story follows the relationship between Kang Dol and Min Dosim (the titular "Dori" and "Dosim") and is riveting. There is a simultaneous plotline involving their friends which is much less engaging. Around chapter 37 or so, both the main and the side stories weaken. Uncoincidentally, this is when Hoon suddenly becomes moody out of nowhere. His moodiness, like the rest of the drama and tension which pervades the last half of this manga, only serves to prolong the story. In the epilogue, the author even mentioned feeling antsy about the story dragging on and feeling the need to come to a conclusion.
