Harlequin manga, so you know what to expect if you read several stories.
Story: 7/10
Would put this one in a pile of good Harlequin manga; I can't say it's typical, but the "plot" is used countless of times.
It's somewhat refreshing story, where the heroine, although extremely stubborn, is not your typical HQ heroine. I came to love the story when hero's mother showed up, "the voice of reason," basically telling them they were both fools, which made me laugh hard.
To sum it up in one sentence: the hero and the heroine play the game "who is more stubborn."
Characters: 6/10
Max: A playboy who has a hard time admitting he is in love with Clea; suspicious, stubborn, and tries to do "the right thing."
Clea: A headstrong, but a capable young woman, who thinks Max sees her only as a sex partner and will get bored with her. She doesn't trust he loves her.
I gave six because of good side characters.
Art: 5/10
Didn't really love the art that much, but again, I saw even worse so this is average.
Overall: 7/10
Again, only because of the refreshing story, moderately realistic life circumstances, and not your typical heroine, although the ending was rather classic.
