Justitia is an extremely educated demon, having not only learned demon laws, but apparently all of the law and procedures of the South Korean court system in addition to memorizing the Christian bible and who knows what else. I do wonder if it was also a form of torture for her to endure in addition to being the heir to Bael, but whatever the lore about that, her skills makes her uniquely suited to play the system to her own ends. Manipulating humans while dealing with new feelings that her human body sends her is another issue. She did not understand how crushes causes dangerous impulses like fluctuating with wanting and not wanting the attention of a guy by taunting the police with dead bodies that would lead back to her being a glaring suspect. It's so ridiculous that she knows how the investigations work, but she still leaves the bodies with an extremely unique stamp on the forehead of the bodies around. Her cases draw attention to how the system both in the show and in real life can give slap on the wrists for the most horrific crimes and even in the case of serial killers, they can become "innocent" by just waiting out the clock on the statute of limitations, as well as corruption from the rich and powerful in the justice system.

Although Justitia falling for Da On is a big turning point, it's merely one part of her softening towards humanity. Her heart also pains for other people and she sheds tears for them as well. The Satan hunting Demon charity volunteer group leader and demon crime scene cleaning crew shows that this is a danger and possibility for all demons to become sympathetic to humans, so it's not only Da On causing this in Justitia. I really like that when she asks for 3 years in the human world, it's not to play house with Da On, but to live as an actual human judge full time. She's not at this point centering her life around this man at all, so I'm find with the romance. The awkward immobile closed mouth kiss scenes never look good, directors need to wake up and accept the fact. The actors show in a much later kiss scene that they can do a normal kiss scene just fine. Also the interrupted kiss gag is also never funny, especially when it's multiple times. The ending has Justitia suddenly given another deal about killing 10 killers to remain human forever and also there is the fate of the original human Judge Kang Bit Na uncertain. It seems to suggest a second season rather than closing out cleanly with room for more, which would have been better as there is never any guarantee for a second season, especially for asian dramas.
