    Ukes kept on saying "no!" "Stop!" But does not resist at all still love it tho. And this is one of the rarest mangas that has a good looking chinese [(don't get me wrong, I love everything ) And yes, most of the mangas I read are jap or korean, so it's rare for me]

      I think that part of his being linked to the stone, bonding him with Mr Handsome for all time. Quite the couple :)

    What's with all the guys dreaming about sex with their pets? Not the one where the dog turned human, that one was fine, but the ones where they saw their pets and started imagining it? That was just weird.

    • (^w^) March 20, 2016 10:50 pm

      Well, one of them was drunk so he can blame the alcohol and as for the other guy, i guess he was too horny o(`ω´ )o anyways everything is acceptable in yaoi (^з^)-☆

    I thought I'd never see a direct, honest uke actually asking for sex, by THIS author. Instead of the typical uke pretending he's an innocent victim, saying "No, stop", while spreading their legs/asses 'cause in reality they're waiting for the cock to rock their worlds lol. That's the case with the rest of her other mangas, including the other stories in this one. Finally something different!

    that résumé is hilarious ! "The dog, which miraculously turned into a human" because who cares about why ? (≧∀≦)

    The last chapter was very... mmm ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄

  13. Jessie January 15, 2016 2:05 pm

    i think the last chapter is fucked up. i mean, what happened to his future wife? she must have been worried and i really don't like cheaters.

    • killua_zoldyck0896 January 15, 2016 3:23 pm

      I eel you.. I really despise cheating.. so even though the manga itself is good, I always end up hating the manga..

  14. Blast January 3, 2016 4:59 pm

    That last chapter is sooooo hot! My eyes are burning xD ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄

  15. Aga December 27, 2015 7:23 pm

    Wow, All those ukes are so lusty! ヾ(☆▽☆)

    The stories were all good and cute but that last one feels like it could really become something more. It was an interesting story line. ^_^

    these stories are all really erotic but I keep feeling like they deserve more chapters. I really liked the concept ideas so it would have been nice if they all had extra chapters.

  18. CrazyfanOrSomething December 4, 2015 7:19 pm

    lol, does anyone else wonders what will happen to his future wife? Haha....to find her future husband missing xD
