Ok, I'm not a fan of romance, so this will be an objective review.
The quality of the writing is simple, neat, and easy to digest. There isn't much description but really it's not a bother. I actually like that, because I tend to imagine the scenes on my own.
The stability of updates... well nothing to say about that really.
Story development is cool. We start the book with SPOILER, the MC in a bed with his "wife" who is actually not really his wife. The author doesn't really linger on the useless and we dive rapidly into the nitty gritty.
Character Design: As far as I have read, it's all good. Nothing out of place and they seem to have their own personalities.
World Background: Humm I didn't read enough to really critic that. But from what I read it is developed and the author gave it some thoughts.
All in all, it is a good novel. Just not in my genre.
Keep up the good work!
**: I've left you some paragraph comments. Be sure to check them all, since I point out some things you could improve in them.
