So there is much to say about this manhwa and truthfully, I don't where to start. I guess I'll organize this and divide on different areas.
First, the art. I have to admit the art is great- not the best and not AMAZING but it is great and one of the best art styles I have seen. One of the best thing about the art is that each character looks so unique and you can tell who they are immediately by just looking at them for a second. I see a lot of times that mangas (and many, many yaoi mangas) tend to make the characters look alike with the same hair color, eyes, face shape, etc... But not for this manhwa. The author was sure to give each character a unique look, especially with the eyes. Saeju's eyes were smaller and sharp while Moto's were big and sparkly, and Itan's eyes were sharp and emotionless. The hair styles varied in different time periods especially in flashbacks, which I loved. Details were always there and the fighting scenes were done greatly. The love scenes were also great and I loved all of Moto's different clothes. It fit into his personality. Itan's were great as well since they were simple, showing he was not much for fashion. Saeju's varied but that fit him as well. Anyways, for the art itself, I'd definitely give a 9 for its uniqueness and beauty.
Secondly, the characters. I got to say, I loved ALL the characters. Moto was great for his role but the best part of him is that seeing his personality, it was obvious why Itan would love someone like him and tolerate him, even for someone who doesn't love humans. Moto was portrayed as someone so happy and persistent yet you could see the pain he has in him, which the author showed greatly. I have to say though, Saeju's personality was probably the easiest to figure out, out of all the characters. Even if he was someone who was cruel, he was direct with his feelings and thoughts. In the beginning, he was being hesitant with how he felt with Moto, but towards the middle end, he was direct when showing he loved Moto and showed his jealousy easily, especially his jealous towards Itan. I hope to see more of Itan's character in the future, but the best part of his character I liked was how he seemed so tough and dangerous and basically a cruel bastard one second, but the next second he's showing this soft side, such as when he says he missed Moto greatly. Although he has his tough side, if you really read into him, you'll see that he loved Moto so much and that's why I don't hate him, as some other reviewers do. I actually like him and hope to learn more about his past. The thing is, obviously Moto will probably end up with Saeju (realistically, however you never know), which will make me feel bad for Itan. My prediction is that hopefully, Itan will end up with that lawyer who helped him get of jail. Although he's a great seme, I can see him needing affection and warmth from someone, such as the lawyer. Anyways, that might be just my guess and false hopes, but you know, I can dream. All in all, the character development is great and is going great as well. I really hope they continue with this manga because I can't wait to see how this goes. Although the negative part may be the way Moto seems so fickle minded between Itan or Saeju. It seems he loves Itan but seems he likes Saeju's warmth and affection, yet he has sex willingly with Itan. I'm not sure, however I hope he stops being confused. I tend to dislike fickle minded people since I feel they should know who they love and go through with it, but maybe there's a reason he's so fickle. I don't know. We'll see. And there seems to be some characters that are not being explained fully, such as Moto's twin brother, Jin. I really hope there is a chapter showing the past of this missing character soon. Anyways, for characters and character development, I'll give it a 8.5
Thirdly, the plot in general. Great plot. It contains many elements that I personally like- comedy (which is truly, truly funny), action, fighting, gangsters, and many others. I definitely think it has a great plot and the persistence from Moto to Saeju is very funny but fits into the plot well. I love how Saeju slides into being part of the whole situation with Itan and the gangsters and how he fit really well into it. I also love the way the plot doesn't fail to show other small things happening on the side, such as Saeju getting a job as a model or his past with his sister-in-law. I also love how it shows the flashbacks of Moto and Itan. Anyways, I really hope to see where this plot is leading and goes to. I'm expecting some crazy plot twists or something, but we'll see. The romance, action, and love triangle all fit well into each other. Even though it may seem confusing a lot, especially with the missing chapters, I hope it'll make more sense later and go down a good path. So all in all, I give the plot a definite 9.5
Anyways, I hope my review helped and yes, it has spoilers. My overall rating based on the average was a 9. By the way, I know there are some chapters missing. For example, the chapter where it started with Itan and Moto standing in the middle of the street with Moto crying after seeing each other for the first time after Itan got out of jail, there was a missing chapter showing of the story led to that. I've searched a lot and seen all websites where this manga is showing, but I can't seem to find the missing chapters. If anyone can tell me where they read it all, please let me know or send me the link. Thank you!
