both have badass female leads with an ulterior motives and a backstory behind their doings. jiwoo was revenge driven in my name who wanted to avenge her fathers death. after a series of events she gets to know that the person she joined hands with is the real killer and that aggravates her thirst of killing. i feel like the protagonist of this drama also has a similar story.
the storyline of both shows are very similar, as in the eclipse where akk, the student body president who is controlled by the cruel principal of the school to maintain peace in the school and upkeep the "nice" image of the school is met with ayan, a rebellious kid who wants to tear away the "all too good" reputation of the school and uncover its toxic ways
