The romance part of this drama was better than the American dramas of the same genre but story was not that good...it was quite predictable...even the end was quite predictable (may be because I have watched too many American series- best being "The Mentalist" and "Sherlock Holmes")...it could have been made better...
And the personality of the characters were not fixed...at first Professor Bo was introvert and was not able to express his feelings...but later on he becomes more expressive than any lead of any typical drama...firstly he was not interested in explaining things to anyone but then he took a whole session to explain things....this sudden change doesn't happen in anyone (being love the only reason). And many other unbelievable things happened in this drama, u can say many loopholes were there...
