Jessica knows it's wrong. Tiffany knows it's wrong. Their future is hanging by a thread that's so precarious that they could lose it in the blink of an eye. They're not supposed to do this. It's a common thought, but every time it comes up, it gets twisted and broken around until all they can think about is what ifs and maybes. When Jessica reaches for the door handle, she wants nothing more than to charge inside, gun in hand, without thinking twice. After all, it's for Tiffany.

Tiffany's a successful businesswoman; she has a massive amount of wealth, prestige, and power. She's married to Taeyeon, the daughter of the most prominent businessman in South Korea. Everything in life has been handed to both on a silver platter by the universe. They have everything, except there's one thing missing from that perfect world for Tiffany; her mistress, Jessica. The only woman she'd sacrifice all that for. 

Tussling around in the snow, Jessica wishes things could be different.

Tiffany's a struggling musician, and after a nasty fight, she returns home after leaving without so much a word. During their inevitable confrontation, she knows she's a fool for returning to her source of misery because all Jessica does is string her along.

Jessica's caught in a scandal that's initially a misunderstanding. Tiffany is convinced she's cheated and refuses to acknowledge her. That's until the inevitable happens, which makes Jessica rethink their lives as idols in the industry.

Tiffany has a breakdown in the middle of the night, and Jessica is there to assure her everything is fine.
