When your "best friend" makes you realize that you've been crushing on your "roommate" for an unimaginably long time now, all kinds of games emerges at once, especially when you're too much of a coward to face the truth. Perhaps the solution to the problem would take a genius, and certainly NOT Kim Jisoo, who decides that the best way to get rid of that string of infatuation is by convincing Chaeyoung that she has a crush on Jennie Kim. And jealousy is an ugly feeling. It is, by far, the messiest game ever.

Jisoo and Chaeyoung find out that their girlfriends are secretly hooking up behind their backs.

Chaeyoung never once felt happy living a princess' life. Given everything she's ever going to need, somehow, she feels like the pieces of her life are still impossibly out of place. When a mystery brunette gets invited by her bestfriend to her 18th birthday party as plus one, Chaeyoung finds herself oddly comfortable with the stranger's presence. Perhaps, even comfortable enough to agree to run away with her to Paris, where Chaeyoung finds the missing puzzle piece that would finally make the others fall into the right places.
