In my opinion, your story became one of the two best active Webnovel fanfics, that's just my personal opinion. Although I don't like MC op somehow this story attracted me as otaku to the hentai. At the beginning I didn't like the idea of YuenaXMc, but you managed to make it work, not only that, it became my favorite couple of DD. It's fun to read this and it never feels forced. Thanks for the chapters, I hope you can finish this story, you've already hooked me, now take responsibility.
