Kylo was a late blooming Omega that has been successfully hiding his secret, but being busy as the new Supreme Leader proved difficult for him to make it to get to his suppressants and his worst nightmare came true. Hux of all people caught him entering heat, and he happened to be his Fated Mate, so he fled to the only planet he could think of, Mustafar, where his Grandfather had been abandoned, left to die in a pit of lava, and he planned to end it all, until Hux came and take him away. So who would save him from Hux? None other than Poe Dameron shows up, claiming to be his Fated Mate too, and Kylo Ren realizes he is screwed by the Force, because it's true, he has two Fated Mates, and how could he possibly choose between them, one, the man he formed a decade long bond with, offering the domination he craved and the power he always wanted, or another, promising to save him, showing him the new brighter world he needed.
