I just finished Perfect Couple ( aka Perfect Match ) and I enjoyed it -
If you are looking for pure romance or smut this is not really it, this is more of a battle of the sexes with a build up of sexual tension that is subtle, not smutty at all, but more about the non sexual parts of a relationship, like how the characters communicate or what they are thinking but not saying. It's interesting that this is a mature shoujo not a little girl type shoujo more from the writing style and art style than the content, but it's not smutty or cheap.

At first, I thought I would check out a chapter or two to see if I would want to read it at some point intime, but I didn't stop and read the whole thing. It has a nice flow to it and it's only 3 volumes. I give it an overall 8.

This is more about a battle of wills and egos, with an intelligent female lead who is a writer and a male movie producer who is used to people doing what he says. So when he decides he wants to make a movie out of her book the battle of wills starts. And they start fighting right from the start, arguing etc. with neither one willing to back down.

The art was good manhwa shoujo art and it expresses the feelings of the two main characters well. This is more about characters rather than story but the dialogue and back and forth tension between the two characters kept me reading. So I enjoyed it both for the art and to see what they would do next.

The translations in the first couple of chapters were a bit off putting, and I think that the English could have been better, but it improves a lot after that.

Actually, I sort of wished there was more love and romance to it also, but it's not quite that sort of story, it's more about the lead up before that with them coming to a place where they respect each other. So it's a lot more subtle than stories that show love coming easily.
I can't really say some things without spoilers so you would have to see what I mean when you finish it when I say it's more of a prelude to a romance.
