At first glance it seemed interesting with the impulse control disorder which quickly turned out to be a very poorly written plot device. Around mid way the disorder became whatever the writer wish it to be then it completely disappeared without any mention or cure as if it never happened despite being a major plot point at the beginning and part of the drama's dvertisement. Apparently it's easier to write a generic story-line instead of attempting something slightly different. Anyway, the drama had also an awful love story-line, both were mostly awkward and had no chemistry or whatsoever. The romance was only included out of obligation, might as well remove it.

The drama also had pacing issues whether it's regarding the main story or any of the side ones. The main story felt limited in the number of characters it involved, there were mainly 6 characters it was cycling through. There was a desperate need to include more characters to contribute to the main story. The support characters weren't given enough attention and most of their stories were cut short anyway. I low-key wanted to see more of the erratic behavior of Se Yeon's sister. Aside from the earlier parts, the drama didn't have anything interesting.
