Story was well written and emotional , As per the story romance scenes were not required but they should have included in it someway by changing the script a bit, then it would have been perfect. Both leads looks amazing but they didn't used it.
Emotional scenes were good and acting was to the point.
Very less comedy and could have added more.
Should have added more mom horror scenes with the villans , Bit of different script, considering what most korean dramas are about like sweet romance or office romance.

Once of the reason i love most about south korean drama are stories are better than Hollywood
