4.2 stars 
 This book is surprisingly addictive. This is the 2nd book that I enjoyed this year. 
 I rated this 5 stars before. But really - the writing is OKAY. The dialogue is OKAY. The Love-Hate is an excellent story plot. BUT there's no setting. No place to picture with! The character development is kind of odd. Odd in the way, that they both got no social life outside work. At first, I am totally hooked. As the story goes, It became repetitive esp with these cheesy dialogues. Not to mention, The climax and resolution are beyond explicit of cheesiness!! IT IS WAY TOO PERFECT. Too perfect to be real that it makes it too easy to know what is really going on. 
 Yet, I'll leave this in 4.2 stars because I did enjoyed it after all.
