This is one of my favorite R18+ Games out there. The character design (from art to personality) is great. The dialogues are witty and the world is interesting.
Is it over the top and unrealistic? Sure. But it's an R18+ harem game featuring elves. I doubt realism is the target to aim for here.
Runey managed to accomplish something I personally thought to be impossible, an oxymoron even: a lovable yandere.
