Marquess Joseph Howard has been trying to grow out of his gambling and cheating father's shadow. Unfortunately, that becomes immensely more difficult when his younger half-brother, his father's love child, is brought to his home. The mother of the child requests compensation for raising the child, named Collin, as was promised by Joseph's father before his death. Still compelled to escape his father's past promises and debts, Joseph agrees to pay off the woman, who then leaves young Collin behind for Joseph to raise. Joseph isn't interested in his half-brother, but unlike Joseph, who looks nothing like the long history of Howard Marquess before him, Collin is a spitting image of his deceased father. Joseph is immensely jealous and feels Collin is just a physical representation of his inadequacy as the new marquess.

But Joseph is determined to better the Howard name, so he reluctantly takes in his half-brother. Joseph prepares the young man for his noble education but finds that he is traumatized and wild. In order to make things a bit easier, Joseph brings in another servant, an enslaved man named Ein. He intends for Ein to get close to Collin and help him integrate into his new life within the Howard household. But Ein has a painful past, one that still haunts him and that he openly fears. Joseph is willing to help Ein escape his past forever, but at a cost. During the day, Ein serves and teaches Collin, but Ein acts as Joseph's bedmate at night.

Ein wants to serve in hopes of one day finally breaking free from his past, but when young Collin falls for him, an intense threatens to tear everything apart. Ein is willing to give his body to his masters. But will he end up giving over his heart, too?


The art style, early on, sort of reminds me of early MORAK with the very long side profile noses that connect to the upper lip, but way worse. It does get leaps and bounds better as it goes along, even going so far as to give more distinctive features between characters, like the marquess's flatter, rounded nose profile against Collin's more upturned and pointed one. The later art is also reminiscent of older Brothers Without a Tomorrow (which I hate, but more on that when I review one of their older titles), but it's not as stiff and harsh – a huge plus. There's one particular panel that highlights what this artist is capable of where Ein is having sex with Collin outside, and while they're holding each other, his expression becomes so much lighter and friendly with minute changes from panel to panel. It's still inconsistent throughout, but the art really grows as the story goes along, which I appreciate.

Unfortunately, while the art does get better, the story desperately needs fleshing out. The most developed character is Joseph, while Ein and Collin are given vague flashbacks at most. Ein does get a bit more development when his former master enters the picture, but when compared to all the time spent on Joseph, his scars, the flashbacks of his life growing up with his mother who hated him for not being a reflection of the Howard bloodline, and even minor reactions to things, every other character feels hollow. This makes the love triangle feel very one-sided, which isn't all that uncommon with love triangles. I've read plenty where it's pretty clear who is end game. However, surprise, the end game is actually Ein and Collin.

While I did like how bright and cheery Collin was, especially when Joseph was often much crueler and cold to Ein, Collin feels so hollow as a character. There are instances where his past is vaguely hinted at, such as his mother saying she wasn't a loving mother and the like, but that's the extent of his development. He was a nice addition to the love triangle and acted more as a bar to achieve for Joseph when sex was involved. Joseph steadily softens up, exposing his vulnerable sides to Ein, and the sex, in turn, seems to become more pleasurable for Ein because Joseph now has a rival for Ein's affection. While Ein and Collin do sleep together, Collin just never seemed like the end game to me, so I was somewhat surprised when it turned out he was. I thought Joseph would finally let go of the pressures of nobility to be with Ein, letting Collin take over instead, especially when Joseph devised a plan to rescue and free Ein, but nope. Collin is stripped of his lower title and disappears before Ein decides to leave the mansion as a free man. It felt rushed, unbelievable, and very unsatisfying.

On the topic of unsatisfying things, there is a second side story where Joseph travels to another country with a stunning hunk of a man named Rick. Rick dotes on Joseph, steadily prying open the walls he's put up around him. There's clearly some attraction between the two, and I was so for it. But then the side story ends. We never see the mission Joseph is there for fulfilled. They don't grow closer beyond the affectionate, vulnerable moments we see when Joseph is ill, which is probably more disappointing than the main story's ending. At least the main story had a clear beginning, middle, and end. This side story starts something and just never goes anywhere with it. I would've preferred it had never even started, as it would have been much less disappointing as a result.


This is a hard miss. The art is rough. The story is severely lacking. And, the end game of the love triangle makes little sense, at least for me. This has potential, but it spent far too much time on the (I know, who am I?) and not enough time developing the main cast, so we felt something for them and that the triangle was viable. Add a painfully lacking side story hinting at a possible relationship for Joseph that goes nowhere, and I'm out.

  1. This definitely sounds like a miss too. I don’t mind the cover art but the blonde one (who I assume is Collin?) also looks so young… very odd choice there. I guess with the more soft/innocent characterization I can see why. It is a shame because the Joseph character arc you were describing for the ending sounds much better 😂

    I have to admit I avoid love triangles like the plague because they always either seem like one person is being intentionally or unintentionally cruel in leading someone on, or there’s such an obvious winner it’s unnecessary angst. Do you have a lighter (and perhaps not obnoxiously long as some manhwa can get) love triangle story you would recommend?

    • Thank you so much for checking out my reviews. I always love seeing your comments.

      I should’ve noted this about the cover art in the review: Collin only looks like that for the first few episodes prior to the time skip. That is such a strange choice to put young Collin in the cover when he doesn’t look like that for a majority of the story. He still looks young, but nowhere near as young as he does in the beginning (can you believe he’s supposed to be 18 in the cover art? No way). Joseph was so heavily built out and for him to not be developed past that was such a disappointment. He’s still beholden to the nobility and his father’s shadow, which is such a letdown.

      Love triangles are such a hit or miss. I can recommend some love triangle titles, but most have the unfortunate “this guy is clearly end game” caveat. Here is what I would recommend on the lighter (and shorter) end:

      Perfectly Broken Love by SUMA – very unique use of the love triangle
      My X Report by Golden Egg – very light and funny title, but the love triangle is pretty much nonexistent and doesn’t appear until the latter half
      Staff Only by soorak – very short omegaverse, and I adore it
      Mistaken Lover by MeriG – should be titled ‘Misunderstanding the Manhwa’
      Talk to Me Tenderly by SingSing – on the longer side, but I love this title, really more of a love polygon
      Dirty ♥ Vibration by Fujoking – smut, smut, smut, smut with a love triangle tacked on toward the end
      The Devil’s Temptation by Youn – this is another on the longer end, but it’s my favorite comedy manhwa, so I have to rec it whenever possible
      Alien in My Wardrobe by BINGO – healthy BDSM, aliens, what more could you want?
      Oh! My Assistant by MILA – not dark, but is very painful at times and it’s a classic

      • Thank you for the quick response! I think I’ll try Staff Only first and see how I feel about it. Dirty Vibration was also on my TBR too!

        And that is a very interesting choice if that isn’t what he looks like the majority of the manhwa. There seems to sometimes be an unfortunate trend of covers looking nothing like interior art or just off in some way. It isn’t true for this one, but I know you’ve shown other reviews where I wonder if they had a different artist involved lmao.

  2. I read a few chapters of this and really didn’t ike it. I’m not crazy about the art style, but it was the storyline and characters that I found more off-putting. Collin in particular seemed far too young (and weak-minded) to be a ML in a yaoi story. It kinda creeped me out.
