Amethyst never thought she would be saving the person she hated the most. Amethyst Olivia Alvarez was an employee of the National Institute of Metaphysics and Astronomy (NIMA), who was fired due to misconduct and vexation in the workplace. She lived a simple life not long after, and decided to detach herself from her past employment. However, her life takes a turn after her former boss, Lai Kuanlin, was reported missing after a successful yet dangerous portal experiment. The NIMA decided to reemploy Amethyst with some promises, and she hesitantly takes the job. Along with Kuanlin's new assistant, Yoo Seonho, she embarks on a journey towards another dimension wherein they look for Kuanlin, yet they get other things in return.
