I don't have a huge problem with people who have a big age difference falling in love with each other in real life as long as the relationship starts once they are both consenting adults and they don't have a prior relationship with an imbalance of power, ie teacher/student, family friend ect.
However, I think what works against this drama is the fact that the two leads are 20 years apart in age, there IS a power imbalance in their relationship, he is her boss, and the Female Leading Actress looks even younger than her character is supposed to be.

Shen Yue is 24 in the drama but looks like she's 16-18 years old and Jerry Yan is very handsome but he looks every minute of his 44 years of age. If he looked to be late 30s and she actually looked to be mid 20s, I believe the audience would have been more forgiving and not really spoken about it much...but the way it is, too many focused on that to the exclusion of everything else about the drama.

IF you can manage to get past all that, the drama itself isn't that bad. It has some good lessons about life, there's some good give and take between the couple, and though it's a bit too long it still manages to hold your attention for all 34 episodes.

I've watched this but I don't think I could rewatch it except in clips. I would give it a 7 and if they had managed to make Shen Yue look her age I probably would have given it a higher rating.
