Though I've been rooting for Min Ho since the beginning ,I have to disagree that Dr Ye is a flat character , He's very considerate and respectful , He really tried as much as he could not to hurt BY when he rejected her , and he always appreciated her hard work, He refused to be the Cheif to not cause someone to lose their job , and though he has seen so much of BY silliness, he still respects her, apart from the advice thing I find him one of the sweetest characters in the drama , on the other hand I don't want him and BY to end up together , I want their relationship to remain platonic as a senior and a junior , I just can't see them as a couple but more like friends
