Carciphones_02 I read the comic itself. Not only did she get outsmarted by her sister-in-law (or aunt), she also got outsmarted by the male lead, who kidnapped her son. She can't even fight other assassins and has to rely on the male lead (who is apparently a CEO and yet he somehow knows how to fight and use guns) to protect her. She can't even sneak around the male lead's house without getting caught. And she lost to the male lead's maids too.
I have no freaking clue how she is an "assassin." Even worse, the comic claims that she took two years to become a top assassin, but she displayed none of those skills (and you can't become a top assassin in such a short period of time, it's an insult to the other assassins). It seems like the author has no idea how assassins work, and didn't bother to do his/her research.
