" Kkondae Intern " was, unexpectedly, quite enjoyable.
The comedy parts of the drama were solid, as the 'bromance' between the two leads was A) well-paced and took its time to mature, B) the two leads had chemistry which helped a lot. Also, there was no unnecessary romantic drama added to it, even though there were some specks of romance to the story. But, overall, the story was kept clean and business-focused. Another plus was the team dynamics, although there were some senior characters that tended to be left out of the equation.
The whole chaebol drama was nice too, even though it was kind of predictable. The drama had some moments that felt rushed too. An example is the ending. That episode had actually started nicely and smoothly, however, towards the ending, it was a bit messy.
Finally, the performances were quite good from everyone in the cast. The length of the drama was just enough as well for the story to be well presented.
So, overall, seven and a half out of ten.
