I can't say that I'm happy with the ending (he shouldn't have forgotten), but it did end in a way that a sequel could easily have a proper, vanilla ending. So, hopefully, we get a sequel. :)
AWWWW!!!!!!!!!! ... reminds me of a classic work from those days B.L. (Before FAKKU Became Legit) named "La Nouvelle Lune (The New Moon), by Yukino Hasegawa". Not the same story, but there are similarities ... and they share at least one thing in common IMHO - the W.A.F.F. level is OVER NINE THOUSAND!
Should also recommend the powers-that-be adding a "W.A.F.F." tag.
I absolutely want a sequel where they rebuild their relationship from scratch (and figure out a way to have sex without his amnesia). Umakuchi Shouyu's art just becomes better every chapter.
Now I'm thinking about what I might have done that angered you so much that you neither want to hear a story nor make some puns and on top call my puns shitty and hold my sequelitus against me... What ever it might be: I'm sorry....
So...What's better than an idol? An idol who is also a Succubus! A succubidol, which is a rather great title I must say.
Because Monster Girls and succubi make just about everything so much better.
Still, it's kind of sad that he has to forget what happened, he seems like a really nice guy. Considering that ending, and the way she smiled when she saw him...I kind of just wish the best for them.
