This is so worth the slow burn and it's nowhere finished! 
it has a finished novel though, and I recommend it very much...sadly only crappy translations to be found... the manhua adaptation has gorgeous art and I hope the sm** will be a bit better balanced dynamics or just very short.(don't get angry). The story really doesn't need a dragged out sm**. It's very romantic, cute and all over adorable with good story build up. And the end is not letting the readers down, it really goes full circle!! love it!
