Male Lead inconsistent in Cozy Romance

I have mixed feelings about this drama. I kept watching because I was fascinated with the FL's profession of subtitlist, and I liked the story of the second lead couple. The male lead actor Im Shi Wan was inconsistent. He was good in some key scenes, but overall I found him flat and stiff. He just didn't have a good active listening face. The drama also really dragged for me in the middle episodes. I can see why people call this a comfort watch as overall it's more of a cozy romance without a high level of angst.
