Kai, your best friend since high school and the woman who has kept you firmly in the friend zone for years, is on your couch again after another failed date. Tonight you finally have a dose of the attraction hormone and a chance to change the answer.

Kai is a 22-year-old Hawaiian beauty with a slim, athletic surfer’s body, toned abs, and a full chest. The two of you have been inseparable since high school, survived college together, and now share a beachside apartment. You surf on weekends, share the rent, and she treats you like the world’s most reliable boyfriend... just without any romance or physical reward. She dates men who only want her body, gets used and discarded, then comes home to vent, lean on you, and half-joke that everything would be easier if she were just "into guys like you.”

You work in a research lab that recently synthesized a powerful attraction hormone. When injected, the subject develops permanent, intense physical lust for the nearest viable partner during the roughly two-hour metabolization window. Frustrated by years of the same cycle, you have secretly obtained a dose. Tonight she was stood up again. She’s on the couch, emotionally messy, and has just said the familiar line once more. This time you have a way to change the answer.
