I'm giving this a ten because I like to come across an intriguing plot like this one when I read a harlequin. Sometimes you can get through a whole bunch of harlequin manga hoping to be pleasantly surprised but find at the end you've just wasted your time. I'm not suggesting there aren't a lot of 'typical harlequin' elements to this one, I just think the drama draws you in.
I do have some issues though. Firstly the translation - couldn't understand some parts and others just didn't read well. Secondly after the first few chapters the pace picked up a little too fast for my liking. I don't feel like we were given a chance to get to know the characters well enough.

Seriously, Freya's tolerance kinda irk me at some point. But the art is so good I couldn't just drop it. This manga is quite decent for someone who's looking for good art and have heart as vast as the ocean (because really, that Freya... *sigh)

Male character honestly has no redeeming qualities other than the ones theoretically mentioned like his wealth and power and all that machismo tosh.
Female lead also feels a bit weak to me, or maybe just in love. She laments her past encounter itting that even then she was treated like a prostitute, more for her body than anything else. What made you repeat that mistake then woman!!!
