Started reading the translated novel (up to chapter 25). Unfortunately, its a machine translation so it's pretty rough going (pronouns and idioms are a complete mess). However, you can still follow the gist of the storylines. So far, the drama seems to follow the novel pretty closely. Biggest differences so far are 1) the female lead has several ex-boyfriends, including both Feng Jun and Karma, 2) an interruption caused the female lead to misunderstand the male lead in high school such that she completely gave up on him and began dating Feng Jun. Male lead did fall in love with female lead in high school but not until after she had already given up on him and moved on.
