AU. When Rey finds herself trapped in a relationship with Armitage Hux she plots revenge with the limited agency she has. She may date him but she’s determined to give him as little of herself as she possibly can. Kylo Ren has a reputation as a tomcat and an undisguised loathing for her boyfriend, so Rey is hopeful he’ll put aside their own differences and help her achieve her goal

Kylo Ren tracks Rey to Ahch-To—not to find Luke, but to tell her the truth about her past. The explosive revelation drives Rey to Kylo's side. Because all Rey's really wanted was her family. (Reylo, Cousin Ben, cousin relationship)

Rey is losing control and knows of only one person who can help her. Kylo Ren has his hands full and sets conditions he is sure will drive her back to whatever Resistance hole she's been hiding in. When it doesn't he exploits the opportunity. TLJ spoilers. Dark smut.
