In the beginning I loved the drama for many reasons, it was so good 'female' story about a girl that was brought up to think and act instead of being a passive flower. Her female relatives and their so-normal family relations were so fresh in the field of c custom drama. Acting is good, directing too, overal nice watching experience.
Romance was so-so until the moment when the MC finds out that ML spied on her and betrayed her, and her family. What does a smart, educated, capable and independant girl do? She says 'it's ok, his sister claims he is a good man so I guess I should not even look at him fiercely'.
This reaction is so against common sense, family loyalty and last but not least, MC's (supposed) budding love for ML. Niao Niao from LLTG was perhaps too strict, but at least she respected her boundaries.
