I really loved this drama , yes people might find it confusing when the second timeline starts. But if you pay close attention to the Female leads monologues it will be easier to understand the switch. I personally liked the second time line , the one where her love interest is her boss. In the first time line although I love the boyfriend, I found his mother very irritating . All the actor did a great job playing their respective roles. The Female lead is not your usual chinese cute Female lead , but ,more matured one, and I really liked this. Overall, the drama was worth the time I spend on it, again this drama is not everyone's cup of tea. I think it has low rating mainly because people is confused about the switch between the two time lines and also few people misunderstood the second time line as the Female lead cheating on her boyfriend, WHICH IS NOT THE CASE. So, yes don't go with the rating on viki and just give it a shot and pay close attention the switch, if you do these two things , you will love the drama like I did. Hope my review was helpful :)
