First off i have some different opinion with many viewers. I see lots of negative reviews which i can totally understand why.
For me i like the casting of the main leads and i like the FL bestie for i think their acting is above average to good(story and character aside). I always like Zhou Yu Tong's acting she does not disappoint me at all. She has always been a super good actress just that most of the drama she is in has lousy script.

I have to be honest that i almost drop the drama at around episode 5. That is because the FL has super lousy character and she is annoying as hell. She always blame others instead of looking at her own problem. The best part about this show is her character development, where she slowly realises her own short coming and incapabilities and lack of passion. Her lack of passion for her work as a scientist and always have the thought of giving up getting her PHD is understandable as her priority has always been making more money to support herself and her grandma. Think about it, most have us will behave the same way if our immediate priority is to make money to survive.

Her development into a better version of herself is almost entirely thanks to our ML whom is always directing her and helping her. YES she was annoying and really unlikable initially but to me its understandable how the ML is in love in her from the start. After all he has always known her and have always been talking to her as an "online friend" i believe as annoying as she is during the chatting period as an "online friend" the ML has see something in her. Unlike the recent drama "Cute Programmer", where i could not understand how the FL fall in love with the ML at all and is a total disaster level drama which i ultimately drop. As a comparison this drama is way better. (To viewers that was able complete The Cute Programmer i salute you.)

ML is also over dramatised with super low EQ, where i must say he is a really stupid genius which is also annoying. THIS plus super annoying FL is the reason why i almost drop the show. The first half of the drama for me is filled with mixed feelings, mostly angst and irritation over the main leads.

However towards episode 12 i start to like the show more and more. It start to feels like a "feel-good" ROMCOM and all the angst disappear. FL develop slowly and steadily becoming more and more likeable. She slowly has passion for her work and did her best for her exams with everything she has got. Finally make up with the ML and does not have as much stupid misunderstanding as compared to the first half. One complain for the second half is that the ML took too much time to confess that he is "forever and ever" which leads to FL angst which is also understandable. But she has always liked him(the online friend) and also fell in love with the real life version so how can she not forgive him? Maybe its not even really about forgiving, she never said she forgave him. She just love him and want to be with him even though he hid her identity from her for so long making her feel like a clown. After all the ML did nothing to hurt her but instead has been helping her throughout. And it is also understandable why he hid his identity so "I" ended up forgiving the ML LOL.

Enjoyment value for first half: 5/10
Second half: 8.5/10
The second half did well in redeeming the first half.

BTW sorry for roasting the cute programmer here HA. HA

Kudos-
