Both dramas have similar premise and the same mature writing and sweet romance. Male leads have similar professions as well. Although female leads have entirely different professions and roles in the story, both of them have similar attributes and backgrounds.
The storyline of both dramas has nothing in common really, but both of the dramas somehow give the same kind of feeling. The kind of feeling that you are watching a real-life couple romancing each other. I mean the chemistry between both couples was perfect. The writing was mature and believable. The production quality of both of the dramas was really good.
