noticed, whenever they are in a meeting with the police cheif they speak different than usual with a tone. are they speaking different language or its just an accent?
story was going well and then they dropped that childhood connection around ep 24/25. her father is the reason or smth his father died . i mean based on these C/K/J dramas u will never find love if are not connected somehow from your early young days. kdrama does this way too much though.
based on experience watching k-dramas it seems likely that seo ji-u's driver is actually her father. i mean he’s old enough to be her father, was always with her and now he's back.
