The three Kim sisters were very different from each other. After all, they were adopted. Kim Jisoo, Kim Sana and Kim Yerim are once again undercover together on a mission (because "Three heads are better than one," their adoptive father would always say) and this mission is proving to be one of the most difficult one yet.

author's note: all blackpink, twice and red velvet members are in the story and many ship interactions are there. i'm unsure of what ships to put but just know that this focuses more on the agents side. also, i am aware that Sana isn't a "Kim" but in one radio show interview she mentioned that she'd pick that surname if she had a Korean surname.
