This is a primarily character driven yaoi, which is refreshing in itself, and definitely gives more depth to the story and all. But I feel they somehow botched this. The whole point of the story is to show how the MC (the uke) ticks and lives his life. Hollow, empty, punishing himself. Avoiding everything that could make him feel. Completely destroying his personality and lifeforce. Now, this is no easy feat, and to some degree, the manhwa does show it... But not nearly enough. I considered uke a boring, too cold and bland char, behaving like a piece of stone. The whole point is that we understand the mechanism behind this, but I just didn't. Plus he was pretty idiotic at times. If I had a deeper inkling of him as a character, I could never take this as a minus, but I did and this largely diminished the quality of the manhwa. I know it's much easier to write a novel about how people think, than to show it in a manhwa, but they needed to spend less time on the revenge story and more on the uke's psychological make up. Ditto for seme. he gets much less screen time, so he's very shabbily developed as a char. You get the general outline of what he is and how he acts, but it's too little, not deep enough. This is a problem when you have a limited number of pages and a story that has to followed. But the whole point of the story is the character development. The revenge is pretty secondary, in fact. So this is a major omission, IMHO.
Well, now for the revenge arc. At some points, it's thrilling and so cool! At other points, it's boring and bogged down by not so interesting characters and story arcs. A major script rewrite was needed, IMHO. As I said, less drama, more character development, but they did not go down that route. Also the antagonists were... Cliche? Expected? A more nuances, more grey antagonist is always welcome, but no such thing here.
On the flipside, the art was excellent!! Loved it!
Overall, this was okay, but nothing outstanding.
