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

very good supernatural story. no overt fantasy or sci-fi just enough to spray mystery over the plot, almost like a slice of life. the ending is open-ended but i'd like to think they ran away together since they somehow always gravitate to one another anyway so it'd be useless for yuichi to run away anyway

    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...

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

    The ending was... A Goddamn cliffhanger

    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!!

    This is a cliffhanger i wat to know wat happen to iori is he alive or dead?? It was a little sad to me but i hope they live a good life. wish there was more :(

  12. chiya May 31, 2014 6:10 pm

    what happened to them?
    iori is still alive?
    or especially where they go and live?
    I am very curious about how they live and live together!

  13. Texas April 24, 2014 9:31 pm

    What the hell?! Where did they go? What happened? Does he live? You can't just drop an ending like that!!

    • Luciana N May 15, 2014 7:02 am

      True... We don't know what will happen neither who was the woman Iori had married...

    art is good but the story is absurd, so does the ending.

  15. qian zi April 6, 2014 9:56 am

    What the-?
    I would've liked at least another chapter...

    Can someone explain what the wedding is about? I am extremely confused who Iori married.

    • guess who March 15, 2014 12:16 pm

      that black haired lady. not the light haired girl

    • lividangel June 7, 2014 5:20 pm

      he married the light haired aunt Hisayo, who is the heir of the wealthy Yonkura family. the dark haired lady is his mom. I always thought that there was something between his mom and Hisayo (chp.2). I thought she married Iori to be near his mom (and maybe to have a kid it seems).

    Inconclusive ending sucks! Looks like the mangaka creates a plot and didn't know how to finish.

  18. M. Pig January 3, 2014 2:50 pm

    Nooooooo! I want more of this story

    • Anonymous February 1, 2014 6:47 pm

      What that can't be the end it just can't

  19. waterbug9 December 2, 2013 6:54 pm

    nice story

  20. My secret is that i love Yaoi December 1, 2013 10:33 pm

    wait, is he gonna die? what happens? why is his family ok with him just disappearing like that?!

    you can't just end a manga so abruptly. its almost like the mangaka didn't know what the fuck to do to finish it so did some bullshit and BOOM. done
