Set in Japan during the '20s, Mitsuyaku is the story of two childhood friends from very different walks of life who grow up to become lovers. Yuuichi is an ambitious type from humble beginnings, working his way towards success. His beloved Iori is the scion of an important family -- a beautiful, dark-haired creature with a gentle nature.

Unfortunately, one of the aspects of belonging to an important lineage is marriage. Will the hero have the guts to stay with the love of his life, or will he succumb to his family's pressure to shore up the dwindling finances by marrying rich?

everyone commented this was sad but if you read the last few pages carefully you can see that Iori and Yuuichi left together they couldn't be separated no matter what, this is pure love

«✜[]✜» Fantastic art but the end's too open & sad. Apart from the Seme's late awakening,
it would be better if the author left us some more clues of their hope.
-- [Spoiler] -- The Seme couldn't survive w/o consuming the Uke's energy of life. Although they balanced it well, both still had shorter life spans. What a terrible fate! .•´(>д<)`•.
BTW. Seems like his bride & mom were secret lover. She married son to live with mom & had her bloodline which the Uke also knew. That's why they're so happy being together even w/o him.

    I think the story is good but they have a sad fate. though I guess they could still be together if they didn't sleep together but then he would die without eating him so......just sad. I basically cried because they seemed to love each other so much and he was told it wasn't real. I wonder if that was true or simply a lie they tell themselves so they can keep on living after killing the one they loved?

    his name means unique the only exception of the clan so they will find something to avoid hid death without harming iori too.

    ...I'd tell Iori everything I'd been told and let him decide. He'd likely choose to die for me, so I'd grant his wish, then kill myself. If he chose to live, I'd leave and die quietly, knowing I'd fulfilled Iori's wish.
    I don't put a lot of weight into living or dying. I believe our souls are eternal and our "lifespan" is one among thousands. Don't get me wrong, I'm not eager to die, but I don't fear it. My body may cease to exist, but "I" am eternal... I'll come back around this way again someday. Death is just the beginning of a new adventure. (⌒▽⌒)

    *Spoiler Alert*
    The end: Rather than running away together Iori is chasing Yuuichi just as he said, and will return once Yuuichi is tired of running. Sadly though that might mean death for one of them. T.T so sad!

    I dont really like the ending this is very hard how can the writer be able to let two lovers live like this all thier life and if thy be with echother one of them will die its just very sad I cant take it.

  9. fujo_leslie July 28, 2015 6:02 pm

    So Iori and Yuuichi ran away together in the end.. BUT Yuuichi would have to steal Iori's vitality and Iori will eventually die because of it. But when Iori dies, will Yuuichi survive even though there's no more Iori to get vitality from? Or will Yuuichi die the same time Iori dies? Lots of questions left unanswered. Cliffhanger feels! I'm so frustrated. :(

    Ok... that was cruel!!! Thry cannot be together... or is kill the man you love or die...

    And make me wonder if he will find him... after all he leaved in order do not kill him... so he will die... does this mean he is alredy death and the other one is still searching him???

    So i got that Iori and Yuuichi left together, but what about Yuuichi's powers? Won't he just keep stealing Iori's life? And his uncle said if he didn't take Iori's life, he'd lose his life or something..?

    • Anonymous July 6, 2015 3:35 am

      I think they committed suicide togther... because either way one of them was going to die. So they committed suicide then they both could be together. The faded stamp could b considered evidence to... just don't know why she got it now ┑( ̄Д  ̄)┍

    I really like this book but each time i read it i am left with more questions for one, are the clan not able to eat any sweets or just sweets made with sugar? Can Yuuichi only take Iori life force through sex or do they only have to touch? If Yuuichi's clan have to take their lovers life force to live, how is the uncle still alive? Is Hisayo in love with Iori? Why was Iori mom frightened of Hisayo? Why and how did Yuuichi awaken?

    if anyone has an answer to any of those questions i will be happy to have them answered

    • Anonymous April 3, 2015 3:12 pm

      Hisayo was probably just like Yuuichi and his uncle, and her mate was Iori's mother. Iori's mother wasn't afraid of her, she was inlove with Hisayo just in the same way Iori was inlove with Yuuichi.

  14. Anonymous April 1, 2015 4:43 am

    I think the one that Iori married, Hisayo, was also one of Yuuichi's race, and her "mate" was Iori's mother, so she intended to marry Iori in order to be close to her own mate. She probably hadn't expected for Iori to also be the mate of another from her race...

    its should not have ended like this,,

  16. AmySuju January 8, 2015 4:45 pm

    Iori was engaged and then got married however one day after the marriage he ran away with Yuuichi at the end

      I think so too. Or maybe she was Yuuichi's mother and wanted to make it easier for them to meet (I mean, because the uncle said that his mother was "special" because she was living in an unusual way for someone of their race)

  18. mikki December 18, 2014 8:04 am

    What happened to Iori? You can't give us an ending like that without telling us what happened to the main characters!
