Your right about it being confusing because of the art but I'm not sure he raped him but it was sexual assault both father and the butler? and he didn't break up with him he told him about going away to uni for 4 years and wanted to marry him when he came back there was a girl in the background talking about breaking up with her boyfriend, but yeah it was messy so maybe I misunderstood.

Fair enough. Though, I don't make a big distinction between rape and sexual assault since, in many countries, rape isn't the technical name for the crime when the act is done to a man. Sodomy and/or sexual assault is the usual crime termed when a man is raped, both of which carry much lighter sentences than the crime of rape. But this is fantasy and crimes in the real world are irrelevant. In the case of this manga, whether it was sexual assault or rape, it was meant to be seen as unwanted attention on the victim's part. Thus, it was meant to be seen as repulsive or criminal.
As for the break up, bear with me because I haven't read this in a few months and I flat refuse to torture myself or waste any more time rereading it, having a mob character's conversation going on in the background of a pivotal scene seems like really poor blocking on both the mangaka's and editor's parts. Adding dialogue that can be attributed to your main characters when they are discussing the exact same topic seems distracting and confusing, if that is what happened. Which adds another element of poor craftsmanship to the already long list.
Thank you for your comment. I always appreciate the comments of those who can offer a rebuttal and an explanation for their opinion. I hope we have a chance to chat again about the manga we read.
Frankly, I was far from impressed. The writing feels rushed and disjointed on top of the plot being horribly cliché. Then there's the art. I got motion sickness from how busy any scene with a hint of sex or eroticism was drawn. It made the scene difficult to understand both visually and through so much excess dialogue. It felt like the artist was not confident in their work and thought if they drew a lot, no one would notice how shitty it all was. Less is more. On to the characters... two protagonists who look nearly identical and have similar, one dimensional personalities. The "prince" had some positive character traits until the 5th and 6th chapters. Then, the few, measly pluses he had going for him were shattered, stomped, burned and shit on when he didn't beat the living fuck out of his rapist father and then later proceeded to take the yankee to a hot spring to break up. He went from "prince" to "prince of the douchebags" in 0.00001 seconds flat. Overall, the whole thing sucked, in my opinion. Time, once wasted and lost, can never be regained. *sigh* On the the next manga!
