Love it even thought the current Background Story Chapter was an important but sad part of it, the rest of it is intriguing, hot and very endearing and at parts funny.
So, it's a really nice VN with twists and all - and I'd be happy to help with the few spelling mistakes or word mix-ups, if that was ok.
Also: the little guy being flooded with so much hot stud's "Lovejuices" would probably be temporarily inflated and the massive tools he's taking, also would show up at the outside of his very stretchable little magic-enhanced body, I'd reckon ;-P - So, temporary inflation sprites would be very hot addition for the "intimate scenes" at least...or some of his toppers also gobble up his "Lovejuice" for a nice change.
Gray looks like he'd be one of the characters likely to do it, but also Ash maybe and of course Rask and Rarok and his brother Akhbal. Any primal ones but also the sensual ones, I could imagine being "inclined" to also have their Lovers' Essence "not wasted".
Also, what Spark/Ark says about them bonding all with each other is something I hope that'll happen...I mean at least all who got some Demon-Blood have basically shared a different "Essence" with the MC, too...even though it was for healing them first. There's interesting possibilities for development still and I'm curious and looking forward which ones you're following up on...you don't need (or should even - for surprise's sake) to disclose your plans for the story though. I'm happy to just follow and see where it's heading. But you already show so much potential with this, that it sparked a lotta deep emotional immersion (rare these days!) and many strings of where the story could be going- which makes it exciting to wait for the next Update, too....and most definitely earns the 5 stars I just gave your Novel already. And if people criticize the sprites, that's something that could still be added later, too...story is something most important to me and reading your answers to the comments here, you're growing with the project, which is beautiful, too. There aren't too many such VNs these days.
