My new life as a mercenary

Born in a clandestine laboratory and subjected to experiments aimed at enhancing her cognitive abilities, Evelyn Ashcroft escaped this life thanks to Dr. Alan Griffin and now uses her intellect to help others. That is, until the day she is called to examine Vykhor Kael’seth.
Vykhor Kael'seth, a ruthless mercenary of an alien species known as the Kael’tarien, is captured by human military forces after his ship crashes. Weakened, he is held in a secret base where he endures violent interrogations.
Upon arriving at the base, Evelyn is intrigued by Vykhor's prosthetic, an advanced piece of Kael’tarien technology. She quickly realizes that not all of Vykhor’s injuries are from the crash and suspects that the military is torturing him. Under the guise of treating him, she sets out to repair his prosthetic, determined to give him a chance to escape. Meanwhile, Colonel Kane, the base's commander, closely monitors Evelyn, gradually revealing that she too is a target of a mysterious benefactor.
When Vykhor manages to activate his prosthetic and contact his ship in orbit, a military strike is launched to facilitate their escape. Kane, satisfied with having used Vykhor as bait to lure Evelyn, attempts to capture her. Vykhor, furious and determined to protect her, eliminates the enemy soldiers and escapes with Evelyn aboard a rescue shuttle. In the ensuing chaos, they flee the military base and head towards Vykhor's ship, the Narak'Tharr.
When Evelyn learns from Vykhor that Dr. Griffin is not human, she decides to tie her future to the Kael’tarien and becomes a mercenary at his side.
What adventures and trials await the two mercenaries? How will Evelyn use her extraordinary intellect in this new environment? And how will the relationship between Evelyn and Vykhor evolve?
