Both you and your twin sister grew up separately. One time, you both decided to switch lives, and that's when you met Cooper, your sister's unrequited lover. Over time, while pretending to be your sister, you slowly started to feel yourself falling for Cooper.

"I already know everything," he interrupts with a bitter laugh. "I know my feelings aren't reciprocated by your sister, but why did you both have to deceive me?"
