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?

Good story of fated lovers who literally need each other to live. What will happen when one is forced to marry?

    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.

    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..?

      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

      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.

  10. 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...

    the story is like this:
    Iori and Yuuichi are together
    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)

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

    Fantastic art but the ending was a bit too open & sad. Apart from the Seme's late awakening, it would be better if the author left us some more hints of hope.
    [Spoilers]... The Seme couldn't survive w/o consuming the Uke's energy of life, no way out for them. Although they balanced well, both still had shorter lifespan than normal people. What a terrible fate! (T_T)
    BTW. Seemed like Hisayo-sama & his mom were secret lover. She marries son just to be close to mother and had her lover's bloodline then. That's why they seemed so happy together even w/o him. (O_O;)

    I seriously hope they just ran away together so they could love each other. The thought of Yuuichi saying such mean things and then leaving Iori forever is just too sad!!

    • Who cares about my name April 5, 2015 4:47 pm

      Errr... They did
      On the last pages you can see Iori's bride reading a postcard from Iori
